Anomalous Scaling Behaviors of the Green's Function in Critical Skin Effects
Yifei Yi, Zhesen Yang
We study the Green's functions in non-Hermitian systems exhibiting the critical non-Hermitian skin effect (critical NHSE) using a double-chain Hatano-Nelson model with inter-chain…

Non-Hermitian skin modes induced by on-site dissipations and chiral tunneling effect
Yifei Yi, Zhesen Yang
In this paper, we study the conditions under which on-site dissipations can induce non-Hermitian skin modes in non-Hermitian systems. When the original Hermitian Hamiltonian has sp…
