Exact solution of single impurity problem in non-reciprocal lattices: impurity induced size-dependent non-Hermitian skin effect
Yanxia Liu, Yumeng Zeng, Linhu Li +1
Non-Hermitian non-reciprocal systems are known to be extremely sensitive to boundary conditions, exhibiting diverse localizing behaviors and spectrum structures when translational…

Feynman diagram approach to dynamical Casimir effect in optimechanical cavity
Yu-Song Cao, Yanxia Liu
In this paper we study an optomechnical system enclosed by an optical cavity with one mirror attached to a spring as a closed quantum system. We provide a different angle of studyi…

Exact solution of non-Hermitian systems with generalized boundary conditions: size-dependent boundary effect and fragility of skin effect
Cui-Xian Guo, Chun-Hui Liu, Xiao-Ming Zhao +2
Systems with non-Hermitian skin effects are very sensitive to the imposed boundary conditions and lattice size, and thus an important question is whether non-Hermitian skin effects…
