Hinged quantum spin Hall effect in antiferromagnetic topological insulators
Hinged quantum spin Hall effect in antiferromagnetic topological insulators
In this work, we predict a hinged quantum spin Hall (HQSH) effect featured by a pair of counterpropagating chiral hinge modes in antiferromagnetic (AFM) topological insulator (TI) multilayers. This pair of chiral hinge modes are localized on the hinges of the top and bottom surfaces of the AFM TI multilayers. …
