Antiferromagnetic second-order topological insulator with fractional mass-kink

Abstract Generally, the topological corner state in two-dimensional (2D) second-order topological insulator (SOTI) is equivalent to the well-known domain wall state, which is originated from the mass-inversion between two adjacent edges with phase shift of π. In this work, go beyond this conventiona...
