Topological origin of non-Hermitian skin effects

N Okuma, K Kawabata, K Shiozaki, M Sato - Physical review letters, 2020 - APS
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 …
