Description:
Author(s): X. L. Zhao, Z. C. Shi, C. S. Yu, and X. X. Yi By introducing loss to one sublattice of dimer chains described by the extended Aubry-André or Harper (AAH) model, we study the topological features including the winding number, the edge states, Chern number, and spectrum of the chain. We find that the parameter region for the system to have real b… [Phys. Rev. A 95, 043837] Published Mon Apr 24, 2017
