Interstate Berry curvature of hinge state and its detection
We demonstrate that the topological hinge state can possess a nontrivial interstate Berry curvature in the non-Abelian formulation of the Berry curvature. It can be readily probed by the circular photogalvanic effect (CPGE), with the light illuminating a specific hinge, and we refer to it as the hin...
