Liouvillian skin effect in a one-dimensional open many-body quantum system with generalized boundary conditions

L Mao, X Yang, MJ Tao, H Hu, L Pan - Physical Review B, 2024 - APS
The non-Hermitian skin effect, in which eigenstates of non-Hermitian Hamiltonians are
localized at one boundary in the open boundary condition, has attracted great interest …

Interaction-induced Liouvillian skin effect in a fermionic chain with a two-body loss

S Hamanaka, K Yamamoto, T Yoshida - Physical Review B, 2023 - APS
Despite recent intensive research on topological aspects of open quantum systems, effects

Boundary-sensitive Lindbladians and relaxation dynamics

X Feng, S Chen - Physical Review B, 2024 - APS
It is well known that non-Hermitian systems can be extremely sensitive to boundary
conditions owing to non-Hermitian skin effect (NHSE). Analogously, we investigate two …

Delocalization of skin steady states

X Feng, S Chen - Physical Review B, 2024 - APS
The skin effect, characterized by the tendency of particles to accumulate at the boundaries,

Manipulating the relaxation time of boundary-dissipative systems through bond dissipation

Y Peng, C Yang, Y Wang - Physical Review B, 2024 - APS
Relaxation time plays a crucial role in describing the relaxation processes of quantum
systems. We study the effect of a type of bond dissipation on the relaxation time of boundary …

Optical pumping through the Liouvillian skin effect

DH Cai, W Yi, CX Dong - arXiv preprint arXiv:2407.12303, 2024 - arxiv.org
The Liouvillian skin effect describes the boundary affinity of Liouvillian eignemodes that
originates from the intrinsic non-Hermiticity of the Liouvillian superoperators. Dynamically, it …
