Type-II quadrupole topological insulators
Yan-Bin Yang, Kai Li, L.-M. Duan, Yong Xu
Abstract
This paper demonstrates a quadrupole topological insulator with zero-energy corner modes and a pair of edge polarizations. The authors also find that such topological phenomena can arise from quench dynamics in non-equilibrium systems.
