Lee-Yang zeros of modulated XY spin chains with Dzyaloshinskii-Moriya interaction: zero-contour topology and quantum phase-diagram reconstruction
Hong Jiang, Xiang-Ping Jiang, Yan-Chao Li
We investigate the Lee--Yang zeros (LYZ) of inhomogeneous anisotropic XY spin chains with Dzyaloshinskii--Moriya (DM) interactions in the complex transverse-field plane, focusing o…
Exact mobility rings in non-Hermitian quasiperiodically decorated Lieb lattices
Ming-Jie Tao, Yi-Ting Wang, Jing Li +3
The mobility ring (MR), a critical boundary in the complex energy plane separating extended and localized states, is fundamental to understanding the Anderson transition in non-Her…
Generic non-Hermitian mobility edges in a class of duality-breaking quasicrystals
Xiang-Ping Jiang, Mingdi Xu, Lei Pan
We provide approximate solutions for the mobility edge (ME) that demarcates localized and extended states within a specific class of one-dimensional non-Hermitian (NH) quasicrystal…
Exact anomalous mobility edges in one-dimensional non-Hermitian quasicrystals
Xiang-Ping Jiang, Weilei Zeng, Yayun Hu +1
Recent research has made significant progress in understanding localization transitions and mobility edges (MEs) that separate extended and localized states in non-Hermitian (NH) q…
Dissipation induced transition between delocalization and localization in the three-dimensional Anderson model
Xuanpu Yang, Xiang-Ping Jiang, Zijun Wei +2
We investigate the probable delocalization-localization transition in open quantum systems with disorder. The disorder can induce localization in isolated quantum systems and it is…
Localization and mobility edges in non-Hermitian continuous quasiperiodic systems
Xiang-Ping Jiang, Zhende Liu, Yayun Hu +1
The mobility edge (ME) is a fundamental concept in the Anderson localized systems, which marks the energy separating extended and localized states. Although the ME and localization…
Dissipation induced ergodic-nonergodic transitions in finite-height mosaic Wannier-Stark lattices
Xiang-Ping Jiang, Xuanpu Yang, Yayun Hu +1
Recent research has observed the occurrence of pseudo-mobility edge (ME) within a modulated mosaic model incorporating the Wannier-Stark potential. This pseudo-ME, which signifies…
Exact non-Hermitian mobility edges and robust flat bands in two-dimensional Lieb lattices with imaginary quasiperiodic potentials
Xiang-Ping Jiang, Weilei Zeng, Yayun Hu +1
The mobility edge (ME) is a critical energy delineates the boundary between extended and localized states within the energy spectrum, and it plays a crucial role in understanding t…
Stark many-body localization with long-range interactions
Xiang-Ping Jiang, Rui Qi, Sheng Yang +2
In one-dimensional (1D) disorder-free interacting systems, a sufficiently strong linear potential can induce localization of the many-body eigenstates, a phenomenon dubbed as Stark…
Localization and mobility edges in non-Hermitian disorder-free lattices
Rui Qi, Junpeng Cao, Xiang-Ping Jiang
The non-Hermitian skin effect (NHSE) is a significant phenomenon observed in non-Hermitian systems under open boundary conditions, where the extensive bulk eigenstates tend to accu…
Multiple localization transitions and novel quantum phases induced by staggered on-site potential
Rui Qi, Junpeng Cao, Xiang-Ping Jiang
We propose an one-dimensional generalized Aubry-Andr{é}-Harper (AAH) model with off-diagonal hopping and staggered on-site potential. We find that the localization transitions coul…

Yanxia Liu, Xiang-Ping Jiang, Junpeng Cao +1
We investigate localization-delocalization transition in one-dimensional non-Hermitian quasiperiodic lattices with exponential short-range hopping, which possess parity-time ($\mat…
