Dynamic protected states in the non-Hermitian system
Lei Chen, Zhen-Xia Niu, Xingran Xu
The non-Hermitian skin effect and nonreciprocal behavior are sensitive to the boundary conditions, which are unique features of non-Hermitian systems. The eigenenergies will become…

Exciton polariton critical non-Hermitian skin effect with spin-momentum-locked gains
Xingran Xu, Lingyu Tian, Zhiyuan An +2
The critical skin effect, an intriguing phenomenon in non-Hermitian systems, displays sensitivity to system size and manifests distinct dynamical behaviors. In this work, we propos…
