Defective Edge States and Anomalous Bulk-Boundary Correspondence in non-Hermitian Topological Systems
Xiao-Ran Wang, Cui-Xian Guo, Su-Peng Kou
Non-Hermitian topological systems show quite different properties as their Hermitian counterparts. An important, puzzled issue on non-Hermitian topological systems is the existence…

Non-Hermitian Dynamic Strings and Anomalous Topological Degeneracy on non-Hermitian Toric-code Model with Parity-time Symmetry
Cui-Xian Guo, Xiao-Ran Wang, Su-Peng Kou
In this paper, with the help of Hermitian/non-Hermitian dynamic strings, the theory of non-Hermitian topological order is developed based on a non-Hermitian Wen-plaquette model. Th…
