Topological origin of non-Hermitian skin effects
A unique feature of non-Hermitian systems is the skin effect, which is the extreme sensitivity
to the boundary conditions. Here, we reveal that the skin effect originates from intrinsic non …

Correspondence between winding numbers and skin modes in non-Hermitian systems
We establish exact relations between the winding of “energy”(eigenvalue of Hamiltonian) on
the complex plane as momentum traverses the Brillouin zone with periodic boundary …

Non-Hermitian bulk-boundary correspondence and auxiliary generalized Brillouin zone theory
We provide a systematic and self-consistent method to calculate the generalized Brillouin

Topological switch for non-Hermitian skin effect in cold-atom systems with loss
We propose a realistic cold-atom quantum setting where topological localization induces
nonreciprocal pumping. This is an intriguing non-Hermitian phenomenon that illustrates how …

Non-Hermitian skin modes induced by on-site dissipations and chiral tunneling effect
Y Yi, Z Yang - Physical Review Letters, 2020 - APS
In this Letter, we study the conditions under which on-site dissipations can induce non-
Hermitian skin modes in non-Hermitian systems. When the original Hermitian Hamiltonian …
