Anomalous non-Hermitian skin effect: topological inequivalence of skin modes versus point gap
Abstract It has long been believed that skin modes are equivalent to the nontrivial point gap. However, we find that this concomitance can be broken, in that skin modes can be absent or present when the point gap is nontrivial or trivial, respectively, named anomalous non-Hermitian skin effect. This...
