Discovery of higher-order topological insulators using the spin Hall conductivity as a topology signature

Abstract The discovery and realization of topological insulators, a phase of matter which hosts metallic boundary states when the d-dimension insulating bulk is confined to (d − 1)-dimensions, led to several potential applications. Recently, it was shown that protected topological states can manifes...
