Fundamental bound on topological gap
Published 31 May 2023 in cond-mat.mes-hall, cond-mat.mtrl-sci, and cond-mat.str-el | (2306.00078v3)
Abstract: We provide a universal tight bound on the energy gap of topological insulators by exploring relationships between topology, quantum geometry, and optical absorption. Applications of our theory to infrared absorption near topological band inversion, magnetic circular dichorism in Chern insulators, and topological gap in moir\'e materials are demonstrated.
