Exact solution of non-Hermitian systems with generalized boundary conditions: size-dependent boundary effect and fragility of skin effect
Cui-Xian Guo, Chun-Hui Liu, Xiao-Ming Zhao +2
Systems with non-Hermitian skin effects are very sensitive to the imposed boundary conditions and lattice size, and thus an important question is whether non-Hermitian skin effects…
Helical damping and anomalous critical non-Hermitian skin effect
Chun-Hui Liu, Kai Zhang, Zhesen Yang +1
Non-Hermitian skin effect and critical skin effect are unique features of non-Hermitian systems. In this Letter, we study an open system with its dynamics of single-particle correl…
Topological classification of defects in non-Hermitian systems
Chun-Hui Liu, Shu Chen
We classify topological defects in non-Hermitian systems with point gap, real gap and imaginary gap for all the Bernard-LeClair classes or generalized Bernard-LeClair classes in al…
Topological classification of non-Hermitian systems with reflection symmetry
Chun-Hui Liu, Hui Jiang, Shu Chen
We classify topological phases of non-Hermitian systems in the Altland-Zirnbauer classes with an additional reflection symmetry in all dimensions. By mapping the non-Hermitian syst…
