Exotic Superconductivity in Three Dimensional Flat-Band Materials
In materials with “flat-bands” where electrons have suppressed kinetic energy, effects of electron-electron interactions give rise to exotic quantum phases including superconductivity. While two-dimensional flat-band materials have been broadly studied in recent years, flat-bands are only just beginning to be realized in three dimensional networks. 3D flat-band materials are an interesting laboratory for the competition between superconductivity and magnetism and may even permit their coexistence. This project will focus on synthesizing and characterizing 3D flat-band materials to identify what exotic quantum phases can be discovered and to understand how electron interactions in flat-bands may lead to deviations from Fermi liquid theory, which describes normal metals. In particular, samples will be studied by analyzing electrical and thermal transport properties with attention to deviations from Fermi liquid theory, especially the Wiedemann Franz law which relates thermal to electrical conductivity in normal metals.
