Exact solutions of non-Hermitian chains with asymmetric long-range hopping under specific boundary conditions
Cui-Xian Guo, Shu Chen
We study one-dimensional general non-Hermitian models with asymmetric long-range hopping and explore to analytically solve the systems under some specific boundary conditions. Alth…
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…
Anomalous Spontaneous Symmetry Breaking in non-Hermitian Systems with Biorthogonal Z2-symmetry
Meng-Lei Yang, Heng Wang, Cui-Xian Guo +3
Landau's spontaneous symmetry breaking theory is a fundamental theory that describes the collective behaviors in many-body systems. It was well known that for usual spontaneous sym…
State-dependent Topological Invariants and Anomalous Bulk-Boundary Correspondence in non-Hermitian Topological Systems
Xiao-Ran Wang, Cui-Xian Guo, Su-Peng Kou
The breakdown of the bulk-boundary correspondence in non-Hermitian (NH) topological systems is an open, controversial issue. In this paper, to resolve this issue, we ask the follow…
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…
