"Guided Discovery: Validating a Method for 3D Flat-Band Material Exploration"
Rice University scientists have discovered a 3D crystalline metal, a copper-vanadium-sulfur alloy, in which quantum correlations and crystal structure frustrate electron movement, resulting in a flat electronic band. The study, published in Nature Physics, details the theoretical design principle and experimental methodology used to find the material, which features a 3D pyrochlore lattice. The discovery may lead to new states of matter and potential applications, and the research team's predictive methodology could aid in identifying other materials with similar properties.
