Weyl fermions are massless chiral particles that can emerge under the appropriate conditions in crystalline materials. Because of their massless character, the Weyl fermions are very efficient at conducting electric charge and could be used to create high-speed electronic circuits and even quantum computers. Using high-throughput computational methods, EPFL scientists have now predicted the presence of a new kind of Weyl fermions in two semimetals, molybdenum and tungsten diphosphide, making them easy to study experimentally.
