Anomalous Behavior of the Non-Hermitian Topological System with an Asymmetric Coupling Impurity

A notable feature of systems with non-Hermitian skin effects is the sensitivity to boundary conditions. In this work, we introduce one type of boundary condition provided by a coupling impurity. We consider a system where a two-level system as an impurity couples to a nonreciprocal Su–Schrieffer–Hee...
