Effective non-Hermitian physics for degenerate ground states of a nonHermitian Ising model with symmetry
Can Wang, Meng-Lei Yang, Cui-Xian Guo +2
In this paper, based on a one-dimensional non-Hermitian spin model with -invariant term, we study the non-Hermitian physics for the two (nearly) degenerate ground sta…

Defective Edge states and Anomalous Bulk-boundary Correspondence for Topological Insulators under Non-Hermitian Similarity Transformation
Can Wang, Xiao-Ran Wang, Cui-Xian Guo +1
It was known that for non-Hermitian topological systems due to the non-Hermitian skin effect, the bulk-edge correspondence is broken down. In this paper, by using one-dimensional S…

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…
