This paper is theoretical and she finds that particular Cu substitutions onto specific Pb atomic sites are key to enabling a band structure that is usually linked to high Tc superconductors.&lt;p&gt;What this means for the more practical minded is that the synthesis of superconducting LK-99 is not trivial and you need to make the appropriate substitutional alloy for this to work.&lt;p&gt;This is a DFT paper, and a band structure that is usually seen in high Tc superconductors just naturally came out. She also talks about the strong electron-phonon coupling that naturally arose from the structure, which is always necessary for superconductivity.&lt;p&gt;I am, by far, the most excited I&amp;#x27;ve ever been about this being a RT, ambient pressure superconductor.</text><parent_chain></parent_chain></comment><story><title>Origin of correlated isolated flat bands in LK99</title><url>https://arxiv.org/abs/2307.16892</url></story>

Though I know absolutely nothing about material science, I have enjoyed the sheer enthusiasm and optimism the scientific community has shown. I feel like I&amp;#x27;m part of something unique and special, something which could have only been achieved by the medium of accessible mass communication. The excitement here is palpable. I feel fortunate to be part of this infinitesimally miniscule portion of human history where I can share this moment with so many people.</text><parent_chain></parent_chain></comment><story><title>Origin of correlated isolated flat bands in LK99</title><url>https://arxiv.org/abs/2307.16892</url></story>
