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…
Three-body bound states of two bosons and one impurity in one dimension
Yanxia Liu, Yi-Cong Yu, Shu Chen
We investigate one-dimensional three-body systems composed of two identical bosons and one imbalanced atom (impurity) with two-body and three-body zero-range interactions. For the…
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…
