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 …

Dissipation induced transition between extension and localization in the three-dimensional Anderson model

X Yang, XP Jiang, Z Wei, Y Wang, L Pan - arxiv preprint arxiv:2409.20319, 2024 - arxiv.org
We investigate the probable extension-localization transition in open quantum systems with
disorder. The disorder can induce localization in isolated quantum systems and it is …

Strong interaction induced dimensional crossover in one-dimensional quantum gas

Z Zhang, Z Zhao, H Wang, K Deng, Y Liu, W Chen… - Physical Review …, 2025 - APS
We generated a one-dimensional quantum gas confined in an elongated optical dipole trap
instead of 2D optical lattices. The sample, comprising thousands of atoms, spans several …

Precision measurement for open systems by the non-Hermitian linear response

P Xu, G Chen - Physical Review A, 2025 - APS
The lower bound of estimated precision for a coherent parameter unitarily encoded in closed
systems has been obtained, and such a lower bound is inversely proportional to the …
