The leaders of the Senate Intelligence Committee warned that Russian operatives may try to sow chaos and manipulate upcoming elections in November and in 2018.
Speaking a news conference on Wednesday, Sen. Richard Burr, R-NC, the committee's chairman, and Sen. Mark Warner, D-VA, its vice chairman, endorsed the conclusions of American intelligence agencies that Russian President Vladimir Putin directed a campaign of hacking and propaganda to disrupt the 2016 presidential election.
"The Russian intelligence service is determined, clever, and I recommend every campaign and every election official take this very seriously as we move into this November's election," Burr said.
Warner said he was concerned that social media companies seemingly did not take the threat of Russian hacking seriously enough, but now there is an "seeing increasing levels of cooperation."
Facebook has uncovered roughly 470 profiles tied to Russian-backed sources. Those profiles purchased about 3,000 ads, now in lawmakers' possession, which sought to stoke political unrest in the United States. Facebook estimated that 10 million users saw the ads before and after Election Day.
Meanwhile, Twitter has found about 200 accounts with suspicious Russian ties. Google has not released any information about Kremlin activities on its advertising platform or other websites, like YouTube.
Warner confirmed reports that Russian hackers attempted to meddle in the elections of at least 21 states. However Burr maintained that the vote tallies were changed in any state.
The Senate Intelligence Committee is examining whether member of Donald Trump's presidential campaign colluded with Russia.
"The issue of collusion is still open," Burr said at the televised press conference. "We continue to investigate both intelligence and witnesses."

Michelle Visage hits back at Amanda Brunker for labelling her IGT outfit 'inappropriate'
"The mammy in me thought what she was wearing was inappropriate for such a family show."
By Megan Roantree |
The final of Ireland's Got Talent took place last week and while most fans used social media to share their favourite act, some viewers took issue with the outfit worn by judge Michelle Visage.
The American judge received various negative comments about her cleavage being on display and has hit out at Amanda Brunker's column about it telling her it's not 'very strong for the feminist movement'.
Last week, she and Amanda got into a discussion on Twitter about the look in question, with Amanda adding that she felt it was 'distracting' for her young sons.
Here are just some of the other comments on made on Twitter.
At the time, Michelle responded saying: "Who KNEW boobs could cause quite a stir….. Ladies, if you've got em, flaunt em! I'm working on something special for the larger breasted ladies…. Stand by."
While it may have seemed to be all cleared up during that Twitter exchange, Amanda's latest column for the Independent also took aim and Michelle and her IGT outfit.
In it, Amanda said: "The mammy in me thought what she was wearing was inappropriate for such a family show.
She added: "Her finale red dress was just too distracting. I couldn't look at her face, I was just fixated on her sternum tattoo and her nude bra that kept winking at me."
She also said that Michelle had already won over the viewers.
"We loved her. She didn't need any more tricks, as a judge or a likeable character."
Michelle blasted the story, which was titled: 'IGT's Michelle Visage has great breasts – I don't need them splashed across my tv though'
She replied to the story on Twitter saying: "Instead of lifting women up and saying "brava for being YOU" they instead say this. Not very strong for the feminist movement…"

\section{Introduction}
The almost unmatched precision of controlling and measuring cold atomic systems provided by recent experiments has made them forerunners in the area of quantum simulations \cite{OpticalLatticeLewenstein:07,bloch_quantum_2012,Gross995}. In particular their many-body aspect and the ability to create out-of-equilibrium situations in a controlled way has led to paradigmatic results that are beyond even advanced numerical simulations \cite{RevModPhys.83.863}.  They therefore  offer an exciting testbed for exploring ideas in quantum thermodynamics \cite{SebStevQTBook}, ranging from  insights into the understanding of work and heat at the quantum level to the operation of quantum heat engines (QHE) and refrigerators \cite{ottoX,Hallwood,LutzPRLHeatEngine,LutzScience,Kosloff2017,ChenCampo2019}. Describing such machines taking fundamental quantum effects into account has already led to a number of unexpected results and can allow one to achieve certain advantages over comparable classical systems. In recent years this has been shown for machines operating across quantum phase transitions \cite{CampisiNC,FuscoPRE,QPTHE1,QPTHE2,QPTHE3,Revathy2020,Abiuso2020}, using squeezed baths as quantum environments \cite{squeeze1,squeeze2,squeeze3,squeeze4,GershonNC}, or exploiting the cooperative effects of many-body quantum systems \cite{Uzdin2016,Campaioli2017,Vroylandt_2017,adolfo3,delCampoEntropy,DeffnerEnt,Niedenzu_2018,Ferraro2018}.

However, the description of interacting many-particle systems at finite temperatures is a non-trivial problem and solvable models only exist in restricted circumstances that are often not experimentally realistic. One notable exception to this are the recently realised Tonks-Girardeau (TG) gases of strongly interacting bosons in effectively one-dimensional settings \cite{paredes_tonksgirardeau_2004,Kinoshita1125}, where exact solutions can be found using the Bose-Fermi mapping theorem at finite temperatures \cite{girardeau1960relationship,Lenard1966,Vignolo2013,Atas2017}. Therefore they lend themselves to exact studies of thermodynamical machines.

In this work we consider a Tonks-Girardeau gas in a box and realise the compression and expansion strokes a heat engine requires by the switching on and off of an optical lattice potential. This changes the one-dimensional volume the system has available and also leads to significant changes in the energy spectrum. Even more, in such a system the particle filling statistics plays an important role, as at low temperature and unit filling an insulating phase forms as soon as an infinitesimally weak lattice potential is applied \cite{buchler2003commensurate,haller2010pinning}. This phase transition is called the pinning-transition and it is signalled by the appearance of an energy gap in the spectrum.  One can therefore drive a quantum Otto cycle between the superfluid and insulating phases by simply switching the lattice on and off. As the operation of the engine cycle is dependent on the energy spectrum of the particles, the presence of the energy gap at the quantum critical point can drastically change the engine performance. Furthermore, due to the competing influence of the lattice potential and the particle interactions, nontrivial energy spectra can be achieved that may exhibit a many-body cooperative effect on the engine cycle. This can be quantified by comparing the many-body quantum heat engine (mQHE) with an equivalently sized ensemble of non-interacting single particle quantum heat engines (sQHE) \cite{adolfo3}.

Of course, any realistic implementation of a QHE cycle must be carried out on a finite timescale, which can have a negative impact on the resulting engine performance. If the cycle is performed too quickly, the excitation of non-equilibrium states may act as a form of inner friction due to the irreversible nature of the dynamics, thereby reducing performance \cite{MossyNJP,FuscoPRX}. While adiabatic dynamics preserve the reversibility of the cycle through the slow driving of the quantum state, the long timescales required result in negligible output power. To achieve both, engine cycles that are efficient and fast, one can employ the techniques of shortcuts to adiabaticity (STA), which allow for adiabatic dynamics on finite timescales \cite{GooldSciRep,Abah2018,PRXAdolf,LutzPRLHeatEngine,CampbellPRA,AbahPRE:19,MGaraot,polkovnikov,delCampoEntropy, Abah19}. However, since the driven dynamics of our interacting many-particle system encompasses the quantum critical point at the pinning transition, standard STA approaches cannot be easily employed. We therefore derive and implement a many-body STA using a variational approach \cite{LewisSTA,Xu:20}, which, although approximate in nature, improves the performance of the engine when compared to a non-optimised cycle.

\section{Methods}
The system we consider consists of a gas of $N$ particles of mass $m$ which are trapped in an effectively one dimensional box potential, $V_\text{B}(x)$, of length $L$ with infinitely high walls. The single particle Hamiltonian is given by
\begin{equation}
    H=-\frac{\hbar^2}{2m}\nabla^2+V_\text{B}(x) + V_l(x,t)\;,
    \label{eq:SingleParticleHamiltonian}
\end{equation}
where we have also included a time-dependent optical lattice potential of the form $V_l(x,t)=V_0(t) \cos^2(k_0 x+\phi)$ (see Fig.~\ref{Fig:Schematic}(a)). The lattice vector is given by $k_0=M\pi/L$ and $M$ is the number of wells. We choose $\phi=0$ for $M$ even and $\phi=\pi/2$ for $M$ odd to ensure that there are no half lattice sites at the edge of the box. We also choose to fix $k_0$ and scale the size of the box potential to change the number of lattice sites.

\begin{figure}[tb]

(d) Single particle spectrum $E_j$ of a lattice with $M=100$ wells and $V_0=0$ (light grey), $V_0=5$ (black) and $V_0=25$ (red).  (e) Efficiency and (f) work output for an adiabatic cycle as a function of the filling ratio $N/M$, with $T_C=0$, $T_H=5$ and $V_f=50$.

    \label{Fig:Schematic}
\end{figure}

The eigenstates, $\psi_n(x)$ (which we calculate through exact diagonalization), of the Hamiltonian \eqref{eq:SingleParticleHamiltonian} can be used to describe a gas of spinless fermions via the Slater determinant $\Psi_{F}(x_1,x_2,\dots,x_{N})=\frac{1}{\sqrt{N!}}\det^{N}_{n,j=1}[\psi_{n}(x_{j})]$, which can be mapped onto a TG gas of hard-core bosons after appropriate symmetrization as $\Psi_{B}(x_1,x_2,\dots,x_{N})=\prod_{1\le i < j \le N}\mbox{sgn}(x_{i}-x_{j})\Psi_{F}(x_{1},x_{2},\dots,x_{N})$ \cite{girardeau1960relationship,Girardeau2000}. This duality can be understood by realising that the spatial distribution of the fermions is governed by a pseudo-interaction implied by the Pauli exclusion principle (Fermi pressure), which has the same effect as the strongly repulsive interaction present in the TG gas. Their respective densities are therefore trivially identical, and this equivalence also extends to their thermodynamic behaviours which are governed by the Fermi-Dirac occupation factors, $f_n=[e^{(E_n-\mu)/k_BT}+1]^{-1}$ (with $E_n$ the eigenenergies, $\mu$ the chemical potential and $k_B$ the Boltzmann constant) \cite{Lenard1966,Atas2017b,Atas2017}. This implies that the engine cycles will be identical as well. In the following we will scale all energies in units of the lattice recoil energy, $E_R=\hbar^2k_0^2/(2m)$, and temperature in units of $E_R/k_B$.

We consider a quantum Otto cycle (see Fig.~\ref{Fig:Schematic}(c)) driven between two lattice depths, $V_0=\lbrace V_i, V_f \rbrace$, at different lattice filling ratios, $N/M$. The cycle consists of four strokes: (i) isentropic \textit{compression} (lattice raising from depth $V_i$ to $V_f$) over a time $t_1$ at fixed temperature $T_C$; (ii) weak coupling to a thermal bath at temperature $T_H>T_C$ during a time $t_2$; (iii)  isentropic \textit{expansion} (lattice lowering from depth $V_f$ to $V_i$) over a time $t_3$; and (iv) weak coupling to a thermal bath at temperature $T_C$ for a time $t_4$. During the isentropic compression and expansion strokes we assume the system is isolated from the respective thermal reservoirs.

We consider a reversible cycle where the dynamics of the quantum state are sufficiently slow so as to be considered adiabatic (denoted by the subscript $AD$). The work done during the isentropic strokes can be calculated from the difference in energy between the many-body states at lattice depths $V_i$ and $V_f$ at the different temperatures, $ \langle W_C\rangle =\langle H_{T_C}(V_f) \rangle - \langle H_{T_C}(V_i) \rangle$ and $\langle W_H\rangle=\langle H_{T_H}(V_i) \rangle - \langle H_{T_H}(V_f) \rangle$, with $\langle H \rangle = \text{Tr}(H \rho)$ being the expectation value of the energy of the thermal states. The heat exchanged with the cold and hot baths is the given by $ \langle Q_C \rangle=\langle H_{T_C}(V_i) \rangle - \langle H_{T_H}(V_i) \rangle$ and $\langle Q_H \rangle=\langle H_{T_H}(V_f) \rangle - \langle H_{T_C}(V_f) \rangle$ and the efficiency and output power can be calculated as
\begin{equation}
  \eta_{AD}=-\frac{\langle W_C\rangle+\langle W_H\rangle}{\langle Q_H \rangle},\quad
  P_{AD}=-\frac{\langle W_C\rangle+\langle W_H\rangle}{\tau}\;,
  \label{eq:effpow}
\end{equation}
where $\langle W \rangle_{\text{ext}}=-\left( \langle W_C\rangle+\langle W_H\rangle\right)$ is the work output and $\tau=t_1+t_2+t_3+t_4$ is the duration of the cycle.

\section{Results}
\subsection{Adiabatic cycle}
For the performance of the engine the filling fraction $N/M$ plays an important role. At $T_C=0$ and for an incommensurate filling, $N\neq M$, the particles are delocalized in the lattice and can move within the box. However, for a commensurate filling, $N=M$, a pinning transition occurs for any infinitesimal lattice strength, whereby each particle becomes more strongly localized at an individual lattice site, which significantly restricts its motion \cite{lelas2012pinning,Mikkelsen_2018}. The behaviour of this insulating phase is then determined by the energy gap in the single particle spectrum (see Fig.~\ref{Fig:Schematic}(d)) which has a size of approximately $V_0/2$ for shallow lattices and $2\sqrt{V_0}$ for deep lattices \cite{buchler2003commensurate}. The differences in the accessible single particle excitation spectrum for $N/M$ therefore lead to different behaviours when running the engine and in Fig.~\ref{Fig:Schematic}(e,f) one can clearly see that peak performance is achieved at unit filling. At this point the particles in the cold adiabat fill the lowest energy band and as $V_0$ is increased the energy gap is widened. Thermal excitations induced by the hot bath then allow particles to jump the gap and therefore more energy can be extracted as the lattice depth is decreased along the hot adiabat. As the high performance regime is the interesting one for heat engines, we will focus on the case of unit filling in the following.

    \caption{(a) Efficiency ratio $\eta^*_{AD}$ as a function of the initial lattice depth $V_i$ and the final lattice depth $V_f$. The system is at unit filling with $N=M=100$, while the temperatures of the cold and hot reservoirs are $T_C=0$ and $T_H=5$, respectively. The grey region indicates the parameter space where $V_i>V_f$, in which no work can be extracted from the cycle. (b) Numerical values for $\eta^*_{AD}$ (red dotted line) and $P^*_{AD}$ (black solid line) compared to the approximation given in Eq.~\eqref{eq:supp} (yellow solid line) as function of $V_f$ for $T_H=5$ with $N=M=100$. The inset shows $P^*_{AD}$ for $T_H=1$ (blue line) and $T_H=20$ (pink line).

The solid lines are for the mQHE, the dotted ones for the sQHE and the black line indicates the Curzon-Ahlborn limit. The inset shows the values of $V_f$ which correspond to the maximum power for each respective cycle (in log-log scale as a function of $T_C/T_H$).

\end{figure*}

The advantage of exploiting the critical point in a many-body quantum heat engine (mQHE) with $N$ particles can be quantified by comparison with an ensemble of $N$ single-particle quantum heat engines (sQHE), see Fig.~\ref{Fig:Schematic}(b).  Each sQHE obeys the Hamiltonian given by Eq.~\eqref{eq:SingleParticleHamiltonian} with a box length of $L=\pi/k_0$, so that exactly one lattice well is present, $V_l=V_0 \cos(k_0 x + \pi/2)$. The Otto cycle is then carried out using the same lattice height and bath temperatures, however in the mQHE the final state is strongly influenced by the presence of the interparticle interactions and the periodicity of the optical lattice.
To quantify the difference between the mQHE and the sQHE, we calculate the ratio of their respective efficiencies and powers
\begin{equation}
 \eta^*(N)=\frac{\eta(N)}{\eta(1)},\quad
  P^*(N)=\frac{P(N)}{N P(1)}\, ,
\end{equation}
such that $\eta^*(N)>1$ and $P^*(N)>1$ indicate that the many-body state gives a performance boost \cite{adolfo3}.

In Fig.~\ref{fig:AD}(a) we show the efficiency ratio for an adiabatic cycle as a function of the lattice depths $V_i$ and $V_f$. For $V_f>V_i$ the cycle produces positive work and therefore acts as an engine. One can see that large many-body cooperative effects can be achieved in the regime where both lattices are weak, and where therefore the particles in the mQHE are still partially overlapping. This results in a non-trivial, non-flat single-particle energy spectrum (see Fig.~\ref{Fig:Schematic}(d)) and therefore in enhanced efficiency and power output over the sQHE. When both lattices are deep, $V_0\gtrsim 30$, the particles are highly localized in individual lattice sites and the single particle energy spectrum becomes degenerate forming flat bands. In this limit all many-body cooperative effects are lost and the mQHE becomes equivalent to the sQHE. Since for weak initial lattice depths, $V_i\lesssim 10$, the mQHE shows enhanced performance for a range of values of $V_f$, we will focus on this region of the parameter space in what follows, specifically considering the limiting case of initially having free particles ($V_i\rightarrow 0$).

Indeed, for mQHE cycles which operate at low reservoir temperatures, $\theta=\frac{E_R}{k_B T_H}\sqrt{V_f} >1$, and which ramp to deep lattices, $V_f\gg1$, it is possible to find an approximate expression for the many-body performance boost,
\begin{equation}
    \eta^*_{AD}(N)=P^*_{AD}(N)\approx1+\frac{1-1/N}{\Delta-\frac{3}{2}\left[ \coth\left(\theta\right)+1\right]}\;,
    \label{eq:supp}
\end{equation}
where $\Delta=2\sqrt{V_f}-1$ is the energy gap (see Supplemental Material for details). From this one can immediately see that at unit filling the mQHE will always outperform the sQHE once $V_f>4$. Furthermore, increasing the number of particles and reaching the state of double filling, $N=2M$, where the two lowest states of each lattice site are occupied, does not lead to improved performance. In the limits $\theta,M\rightarrow\infty$ the efficiency ratio can be written as $\eta^*(2M)\equiv\frac{\eta(2M)}{\eta(1)}\rightarrow\frac{1-4(\Delta-1)^{-1}}{1-3\Delta^{-1}}$, showing that for $V_f>1$ the efficiency of the sQHE is always larger than the mQHE at double filling, which is due to the anharmonicity of the individual lattice sites leading to reduced gaps between higher lying energy states.

In Fig.~\ref{fig:AD}(b) we show the numerically obtained values of the ratios $\eta^*_{AD}(N)$ and $P^*_{AD}(N)$ as a function of $V_f$ in comparison to the approximation in Eq.~\eqref{eq:supp}. One can see that the exact ratios peak at lower values of $V_f$, which is due to the fact that the particles in the many-body state are still partially delocalized and therefore many-body cooperativity is stronger. For deeper lattices, $V_f\gtrsim50$, both ratios head towards one, as stronger localisation makes the lattice sites become effectively independent. The decay of the many-body advantage is well described by the approximation in Eq.~\eqref{eq:supp} (solid yellow line in Fig.~\ref{fig:AD}(b)) and given by a $1/\Delta$ dependence. While the decay is universal, the position and height of the maximum are depending on the other parameters of the system, in particular $T_H$ (see inset of Fig.~\ref{fig:AD}(b)). In general, a significant many-body advantage exists by operating the mQHE in weak lattices and at low temperatures when the commensurate system remains close to the quantum critical point. At higher temperatures the existing thermal energies diminish the importance of energy gap and the quantum criticality is washed out. To demonstrate this we show in Fig.~\ref{fig:AD}(c) the efficiency at maximum power (optimised over the lattice depth $V_f$, see inset in Fig.~\ref{fig:AD}(c)) for two different temperatures of the cold adiabat: one deep in the quantum regime $T_C=0.01$, which ensures that the system is in its ground state and therefore close to the quantum critical point; the other at a slightly higher temperature $T_C=0.1$, where the effect of the quantum criticality is reduced. When $T_H$ is small, the mQHE with the lower $T_C$ can be seen to be more efficient and close to the Curzon-Ahlborn efficiency, $\eta_{CA}=1-\sqrt{T_C/T_H}$, which is a good indicator of the performance of the Otto cycle \cite{CA1,DeffnerEnt,AbahPRE:19}. Furthermore, it is worth noticing that at higher $T_C$ the mQHE is outperformed by the sQHE as the thermal energy leads to less localisation within the box potential and the energy gap is washed out. Therefore, this quantum critical mQHE only shows enhanced performance at low temperatures when the system is close to the critical point.

In deep lattices the power and efficiency ratios are equivalent for any number of lattice sites at unit filling ($N=M$) and they are exactly described by Eq.~\eqref{eq:supp} (see Fig.~\ref{fig:AD}(d)). As the many-body advantage is proportional to $(1-1/N)$, one can see a rapid increase in both quantities for increasing particle number until $N\sim10$, after which it asymptotically approaches $1+\left(\Delta-3\right)^{-1}$ in the thermodynamic limit. In more shallow lattices the efficiency and power ratios asymptotically reach different, but overall larger values, while the dependence on $N$ remains consistent with the behaviour observed for deep lattices (see inset of Fig.~\ref{fig:AD}(d)). Indeed, one does not need to create large many-body states to see a marked improvement in engine performance, rather only a few dozen particles are sufficient for observing the effects of many-body cooperativity in this system.

\subsection{Finite time cycle}
While all the results above are obtained for a reversible cycle with undergoes adiabatic dynamics, this results in negligible power output due to the long timescales for each cycle, therefore necessitating fast engine cycles for finite power-output. However, fast driving through a critical point will inevitably result in non-adiabatic dynamics and irreversible work being produced, with the latter being defined as the difference between the average work of the non-adiabatic ($NA$) and adiabatic driving, $\langle W_{irr} \rangle=\langle W \rangle_{NA} - \langle W \rangle_{AD}$. This ultimately leads to reduced performance of the QHE \cite{campbell2016,Hoang2016,Deffner2017}. To explore the effect of irreversible work on the engine performance we numerically calculate the unitary dynamics of the single particle states during the compression and expansion strokes, $\psi_n(x,t)=e^{-\frac{i}{\hbar} \int_{0}^{t} H(t') dt'} \psi_n(x,0)$, describing the insertion and removal of the optical lattice over a finite time $t_f$ (in units of $2\pi/E_R$). We parametrise the lattice strength as $V_{\lambda}(t)=\lambda(t)V_f\cos^2(k_0 x)$, with $\lambda(t)=t^3/t_f^3[1+3(1-t/t_f) + 6(1-t/t_f)^2]$, which
is sufficient to explore the dynamical properties of a finite time engine stroke, but is not necessarily optimal for the system \cite{Bloch2007,Masuda2014,Troyer2015,Zhou_2018}). As our focus is on the non-adiabatic dynamics initiated by the lattice ramp we will neglect the dynamics during the coupling to the different heat baths and assume that the thermalization times $t_2$ and $t_4$ are much shorter than the times for the work strokes $t_1$ and $t_3$ \cite{GooldSciRep,LutzArXiv}. Taking $t_1=t_3\equiv t_f$, the total time for the cycle is $\tau\approx 2 t_f$.

\end{figure}

For a finite time cycle at commensurate filling the efficiency only slowly approaches the adiabatic efficiency (see Fig.~\ref{fig:ref_ramp}(a)) due to the large amount of irreversible work created when driving the system at the pinning transition (see Fig.~\ref{fig:ref_ramp}(b-c)). In comparison, incommensurate fillings produce significantly less irreversible work as excitations are far from the energy gap and therefore the adiabatic efficiency can be reached for significantly shorter ramp times. Also note that more irreversibility is created during the raising of the barrier compared to the lowering, as the opening of the energy gap adds to the nonequilibrium excitations.

Even with the advantage gained from the energy gap, the resulting irreversible dynamics on short timescales set a limit on the performance of the engine cycle. In fact, this problem does not just appear in dynamics about a critical point, but is present in any non-adiabatic driving of quantum heat engines. To improve engine performance on finite timescales different shortcut to adiabaticity (STA) approaches have been suggested \cite{GooldSciRep,Adolfo2012,delCampoEntropy,jing2,Abah2018,AbahPRE:19,Hartmann2020}. However, while STAs have been successfully developed for non-interacting and mean-field systems, designing them for strongly interacting many-body systems poses new challenges when scale invariance can not be exploited \cite{LewisSTA}, and is especially difficult due to the orthogonality catastrophe in larger systems \cite{polkovnikov,TF_PRL2020}. We therefore employ a variational approach which can find the optimal driving amplitude $V^\text{STA}_n(t)$ for each of the single particle functions $\psi_n(x,t)$ which are used in the Slater determinant to construct the many-body state \cite{Xu:20}. However, while this in principle can optimise the dynamics of each $\psi_n(x,t)$ individually, in practice a single lattice ramp must act on the entire many-body state and the chosen $V^\text{STA}_n(t)$ may  create unwanted excitations in different $\psi_m(x,t)$, for $m\neq n$.

We therefore consider two different approximate STAs to optimize the many-body dynamics. First, we choose the average of the STA pulses for all states up to the energy gap, $\langle V^\text{STA}(t) \rangle=\sum_{n=1}^M V^\text{STA}_n(t)/M$, and numerically time evolve the single particle states with this finite time ramp. While this shows an improvement over the non-optimized ramp $V_{\lambda}(t)$ for all timescales (see Fig.~\ref{fig:ref_ramp}(d-e)), it is only marginal as the optimization is averaged over the whole system. We therefore also consider the ramp $V^\text{STA}_{M-1}(t)$, which specifically optimizes the most irreversible single particle state, $\psi_{M-1}(x)$, which sits just below the gap and possesses the most excess energy after the $V_{\lambda}$ ramp (see insets in Fig.~\ref{fig:ref_ramp}(d-e)). This STA results in a larger efficiency gain as excitations of this state are mostly suppressed, and the adiabatic limit is quickly reached when the lattice is weak. However, this STA becomes ineffective for fast cycles, as large modulations in the approximate STA ramp can induce excitations in the rest of the system, which is a limitation of using these approximate techniques to design STAs for many-body states.

\section{Conclusions}

In summary, we have described the operation of a quantum Otto cycle about a critical point in a strongly interacting many-particle system. We have shown that such a setup can yield increased performance due to the presence of an energy gap and cooperative many-body effects which arise due to competition between interactions and lattice forces. Using the particular cold-atom setup we have chosen, which has already been experimentally studied \cite{haller2010pinning}, clearly highlights the dynamical effects stemming from the ordering when going through the critical point and the complex dynamics that arises during non-trivial shortcut driving. Furthermore, recent experiments have shown that many-particle heat engines can be realized with two-component ultracold gases \cite{Bouton2020}, whereby inelastic spin-exchange collisions are used to transfer heat between the engine and the bath. Accordingly, our work lays foundations for the further exploration of STA techniques for interacting many-body systems and their potential applications in quantum heat engines.

How are your tent caterpillars?
Ernest Hemingway rewrote the ending to A Farewell to Arms thirty-nine times. When asked why, he said he rewrote it to get the words right.
Yesterday I walked along a sunny road on the edge of Mount Maxwell. It was bordered by thick rows of enormous foxgloves, some of which towered over my 172 cm / 5' 8" height. Later, when I mentioned it to my sister, she commented only weeks before when she walked it, she'd had to push her way through all the tent caterpillars.
Not long ago my novel Lockdown was in the same state as that mountain trail in the spring: sticky with tent caterpillars. It had been part of me for so long that I was unable to see its flaws. Then I skyped with my editor, Anita Daher and she turned the light on. The spidery webs started to fall away and a few flower spikes nudged their heads into the sunshine. Those blooms only started to open after more rewriting.
The editing process is far from being a pleasant summer's walk on a favourite mountain trail. It's more like hiking the same terrain in autumn, winter, spring and summer and contemplating the different perspectives that each rewrite brings.
I think my novel is getting close to its full glory, although I have a draft or two to run through yet. To help get there, I remember the beautiful flowers that rise out of the caterpillar silk. As I work through the next reiterations, I'll model my attitude on John Irving's: I think what I've always recognized about writing is that I don't put much value in so-called inspiration. The value is in how many times you can redo something.
How many times have you rewritten your latest scene, story, or book? Are you like Hemingway, rewriting the same page thirty-nine times? When someone suggests you rewrite something, do you perceive that as a punishment or as an opportunity to bring the work to greater power and clarity? Are there bright spring flowers poking through the caterpillar plague?

Students take part in Cedar Valley Youth Theatre play
By Erin McRae on March 1, 2019
From left, University of Northern Iowa (UNI) student Angelica Fink, West High School student Abby Zeets, CFHS sophomore Annie Brown, CFHS sophomore Erin McRae, Valley Lutheran student Megan Wheelock and UNI student Lily Gast sing "God Save the People" in show Godspell.
The Cedar Valley Youth Theater is putting on the musical "Godspell," composed by Stephen Schwartz and written by John-Michael Tebelak at the Women's Club, from March 1-10. It focuses on the story of Jesus told through a small group of people in multiple parables, dissolving hauntingly into the last supper and crucifixion. Bob Filippone is directing alongside choreographer Abby Zeets and musical directors Rosemary and Daniel Gast. This team is not new to local theater, having previously put on productions like "13 the Musical!" at the Oster Regent Theatre, and "Little Women" at the Cedar Falls Women's Club last year. Although he works as a radiologist by day, Filippone has a passion for music and theater that takes over his nights as the owner of NOCE Jazz Club in Des Moines and the founder of Des Moines Young Artists' Theater. Filippone said that choosing "Godspell" was an easy task and was a musical he had been looking forward to doing for a while.
Right, the cast sings "Light of the World."
"I really wanted to put on a high fun energy show that concentrated more on showcasing the actors' talents than on an expensive set and costumes," Filippone said. "The show is about a small group of people helping Jesus to tell different parables through a wide variety of games, storytelling techniques and hefty doses of comic timing." For Filippone, the process has been relatively easy thanks to the help of the 13 young cast members all under the age of 20. "I love working with the young actors and being at the women's club," Filippone said. "It's fun to see how everyone blossoms throughout the rehearsal process." Sophomore Annie Brown plays one of the many people who help tell the story through parables. For her, the decision to audition for "Godspell" was a no-brainer. "I ended up auditioning because I love plays and I already knew and loved the directors of this show. I knew from the start it was going to be super fun and worth my time." Brown said that the music took up a lot of the rehearsal process, due to its difficult nature. "Not only are the songs challenging themselves, but the harmonies all put together are challenging every bit of my musical background." But in the end, Brown said that the hard work really was worth it for the final product that they've achieved. "Now that we've reached the end, it sounds so good," Brown said. "The cast has put in so much time and effort, and you can really see it paying off." Filippone said that the wide variety of music really helps to paint the picture of how complex the story of Jesus and his disciples is. "The songs really range in styles from pop to vaudeville that displays Jesus' messages of kindness, tolerance and love come vibrantly to life," Filippone said. Brown also credits choreographer Abby Zeets for putting together dances that coincide with the music in a way that allows for the score to shine. "I was kind of skeptical to have one of our castmates choreograph the whole show, but to say she pulled it off is an understatement," Brown said. "The moves aren't too challenging, but she puts it together in a way that makes it look so professional and sassy at the same time. I could really go on and on at how amazing both the musical directors and choreographer have been throughout this whole process." Filippone said that the story is a timeless and eclectic blend of heart that reflects Biblical history in a modern light that everyone should come to see. "You really get to see the music come to life as Jesus' life dances across the stage." Brown agreed and said that the show isn't really just about religion, but rather the gathering of people from different backgrounds toward a common goal and purpose. "Even if you don't believe in the Gospel or the parables of Jesus, it still has a powerful message and great songs to dance boogie around with," Brown said. "The show is really about what it means to be a good person, and leaves you with songs that you'll want to dance around to in your living room." "Godspell" runs March 1-10 at the Cedar Falls Women's Club. Showtimes are Fridays and Saturdays at 7:30 p.m., and Sunday matinees at 2. General admission is $10. More information can be found at www.cedarfallswomansclub.com.

EF-PTK-Award2.jpg
Dr. Everette J. Freeman, president of Community College of Denver (CCD), was awarded the Shirley B. Gordon Award of Distinction for his commitment and dedication to CCD's Phi Theta Kappa (PTK) Alpha Mu Mu Honor Society.
Dr. Freeman, or "Everette" as he likes to be called, regularly attends meetings and shows support through his ongoing service and advocacy of the students involved with PTK. The Shirley B. Gordon Award is the most prestigious award given to college presidents by the Honor Society.
Dr. Freeman was not only nominated by the chapter for this distinction because of his involvement with PTK, but also for modeling the Society's ideals of fellowship, leadership, service, and scholarship.
Last semester, Dr. Freeman was awarded an honorary "Stole of Gratitude" at the fall induction ceremony due to his continued enthusiasm for the success of the CCD student body and for his selfless service to the community. Everette is unceasingly working to improve the college experience at CCD and his door is always open to any student who wants to stop by his office. He invites students to come so he can get to know them and their goals, take a picture sitting in the president's chair and to encourage them to strive to make their dreams come true.
"Supporting PTK is so easy because all of you are so darn smart," said Everette. "It is proven that students who participate in extra-curricular activities like PTK are much more likely to succeed and complete college. Being involved in school clubs and organizations can help you gain experience and keep you connected to others on campus."
Dr. Freeman joined the rest of Phi Theta Kappa members at the Centennial Catalyst Convention in Kansas City, Missouri to accept this award earlier this month.
About the Dr. Shirley B. Gordon Award
Dr. Shirley B. Gordon was Phi Theta Kappa's longest-serving Board of Directors Chair and President Emeritus of Highline Community College in Des Moines, Washington. Dr. Gordon was named Phi Theta Kappa's Most Distinguished College President in 1984.

Home > Computing	> Does type safety matter?
One of the distinctive features of programming languages is type safety, esp. static vs. dynamic typing. Let's take C++ and Python as examples.
In C++ a variable type is determined at compile time and remains the same for the lifetime of a compiled program, while in Python a variable can change type at run time. Moreover, object types in Python can evolve at run time while members are added and removed. In practice, we can create a generic dynamic type in C++ which can contain anything and make variables behave like in Python, but we almost never do.
I was recently watching a C++ talk from some conference, where a distinguished professor claimed static typing in C++ to be superior to dynamic typing Python. To make his point, he said that Python requires you to write tests to make a program as robust as in C++. Now that does not make any sense, because you have to write tests regardless of whether your program is written in C++ or in Python. Static typing doesn't give you any guarantees that your program will bug-free!
Some time ago there was a study which was comparing programming languages based on the number of defects occurring in programs written in these languages. In that study no significant difference was found between C++ and Python. I would take this study with a grain of salt, yet one thing stood out – that functional programming languages have less bugs than imperative languages, which is likely. You can argue with my analysis of the results of the study, but compare PERL, PHP, C and C++ and you will know what I meant with regards to the grain of salt. My point is, there is no proof that static typing vs. dynamic typing makes much difference on the quality of code.
Suffice to say, the type system in C++ is not very well designed. Let's take a look at two examples.
It may surprise you that this program prints "true", meaning that -1 is greater than 1. This is because of "very interesting" type promotion rules in C and C++, due to which a signed type is promoted to an unsigned type.
On top of this, in modern C++ it is recommended to use signed int type for most purposes. Contrast this to the ubiquitous unsigned size_t type in the C++ standard library.
A C++ compiler can help you identify problems in your program during compilation, especially if you enable the highest warnings level possible. You will often find out that you have lots of type-related problems in your C++ program. The solution is typically to scatter lots of static_casts across your code base. However, type casting becomes not only an annoying necessity, but it also hides bugs – check out the -1 > 1 comparison above to see what I mean.
You might say that if you use int for everything (arguments, variables, members) you won't have to do any casting. Fine, but you can't escape size_t! Using one type for everything also defies the purpose of having static type checking. You want diverse types to check arguments passed to functions at compile-time. But that leads to incompatible types and type casts – vicious circle!

Police v Kritcos [2016] SASC 28 (10 March 2016) – South Australia Supreme Court
'Confirmation of intervention order' – 'Emotional abuse' – 'Evidence' – 'Following, harassing, monitoring' – 'Interim intervention order'
Appeal Type: Appeal against a Magistrate's decision to revoke an interim intervention order.
Facts: An interim intervention order was made against the respondent (the appellant's former husband). A Magistrate dismissed an application to confirm the order and revoked the order. The alleged abuse consisted of three letters that the respondent sent to the appellant. One of the letters concerned renewal of their deceased pet dog's council registration and the attached dog tag. She believed that the respondent was making a point of using her address when he knew she did not want it disclosed and that the letter was a 'gratuitous and hurtful' reminder of the dog's death. During their marriage, they had intimidated the respondent's former wife by driving past her house. She was worried she would suffer similar harassment. The respondent denied all knowledge of the other letters. The appellant gave evidence which alleged prior acts of abuse by the respondent, including threats to kill and physical abuse. The Magistrate largely rejected this evidence as not proven, taking into account the fact that the appellant admitted lying in an affidavit previously filed in the Family Court. The Magistrate also rejected the respondent's explanation about sending the dog tag and found it was sent out of spite to upset the appellant.
Notwithstanding, while this conduct was spiteful, the Magistrate was not satisfied it resulted in emotional and psychological harm within the meaning of the Intervention Orders (Prevention of Abuse) Act 2009 (the Act). The Magistrate concluded that it was reasonable to suspect that the conduct would cause 'upset, annoyance and anger' but not harm. While the Magistrate found it was reasonable to suspect that the conduct would continue without intervention because the respondent's evidence 'did not provide any direct reassurance that the conduct will not continue' (See at [19]), he found that it would not be appropriate in the circumstances to confirm the order. He gave the respondent an opportunity to show he would not persist with the conduct. If the conduct persisted, the appellant could make an application for a further interim order. The Magistrate also noted the appellant was a personal trainer, coaches kick boxing and holds a black belt in martial arts.
Issue/s:
Whether the Magistrate erred in concluding that the letters did not amount to an act of abuse under the Act.
Whether the Magistrate erred in concluding that it was not appropriate to make an order in the circumstances.
Decision and Reasoning: The appeal was dismissed.
The appellant submitted that the Magistrate erred by not having regard to the definition of emotional and psychological harm in the Act which includes 'distress, anxiety or fear that is more than trivial'. Doyle J held that while the Magistrate should have expressly referred to this definition, the Magistrate's finding was that, 'the correspondence was reasonably expected to cause "upset, annoyance and anger" in contradistinction to non-trivial "distress, anxiety or fear"' (see at [36]). The appellant also submitted that the Magistrate erred in 'approaching the issue of harm on the basis that he needed to be satisfied that the defendant's conduct was "intended to, and caused" harm. Doyle J concluded that the Magistrate had to consider three issues – 'First, whether the letters might reasonably be expected to cause harm (s 8(4)(j)) and then whether they were intended to, and did in fact, result in harm (s 8(2))' (see at [39]). His Honour concluded that the effect of the Magistrate's finding was that, 'the letters were neither intended to, nor did in fact, result in harm' and '(the Magistrate) appropriately addressed both the respondent's state of mind in engaging in the relevant conduct and the (subjective) impact of this conduct on the protected person' (see at [39]). In relation to the exclusion of other evidence relating to the history of the relationship, Doyle J held that the appellant was given several opportunities to detail the effect of the letters upon her.
The appellant submitted that the Magistrate failed to have regard to the principles set out in s 10 of the Act which are relevant to determining whether it is appropriate to make an order. In particular, the section makes clear that abuse can consist of isolated incidents. Doyle J stated at [44] – 'his Honour did not suggest that isolated instances could not constitute abuse. His reasoning was merely that on the facts of this case the letters (neither individually nor cumulatively) were not sufficient to constitute abuse.' In relation to the Magistrate's references to the appellant being a personal trainer and having martial arts qualifications, his Honour stated that this was a 'somewhat obscure' reference, but it was, 'probably best understood as being a reference to matters which might have given the protected person some level of personal confidence and physical prowess. While I consider these matters to have been of only marginal relevance, I do not think they are entirely irrelevant or that it was erroneous to take them into account' (see at [45]). The Magistrate's conclusion to give the respondent an opportunity to not persist with the relevant conduct is not a factor referred to in s 10(1) of the Act, but was nevertheless not irrelevant. It is a relevant consideration that the respondent is someone who might respond to an opportunity to change their behaviour. See finally at [48] –
'Here there was no proven act of past abuse. While the Magistrate accepted there was a reasonable suspicion abuse would occur in the future without intervention, it might be inferred that the Magistrate did not consider there to be a high likelihood of this occurring. Indeed, the Magistrate's judgment appears (from his reference to the contingency that his judgment might prove to be misplaced) to have been that the suspicion will probably not come to fruition. It is also relevant that while there was a suspicion of abuse in the broad sense contemplated by the Act (i.e. extending to emotional and psychological harm), the Magistrate made a positive finding that it was not reasonable to suspect that the defendant would cause physical harm to the protected person.
