Topological phases of many-body non-Hermitian systems
Kui Cao, Su-Peng Kou
We show that many-body fermionic non-Hermitian systems require two distinct sets of topological invariants to describe the topology of energy bands and quantum states respectively,…
Statistical mechanics for non-Hermitian quantum systems
Kui Cao, Su-Peng Kou
We present a systematic study of statistical mechanics for non-Hermitian quantum systems. Our work reveals that the stability of a non-Hermitian system necessitates the existence o…
Non-Hermitian Chiral Skin Effect
Xinran Ma, Kui Cao, Xiaoran Wang +2
The interplay between non-Hermitian effects and topological insulators has become a frontier of research in non-Hermitian physics. However, the existence of a non-Hermitian skin ef…
Symmetry classes of dissipative topological insulators with edge dark state
Fei Yang, Zheng Wei, Xianqi Tong +2
We classify the dissipative topological insulators (TIs) with edge dark states (EDS) by using the 38-fold way of non-Hermitian systems in this paper. The dissipative dynamics of th…
