Nonlinear Photonic Tripartite Phase
Xiangrui Hou, Fangyu Wang, Zhaoxin Wu +8
Anderson localization is usually understood as a transition between extended and localized phases, with criticality confined to a single mobility edge. Recent advances predict that…
Emergent topological re-entrant phase transition in a generalized quasiperiodic modulated Su-Schrieffer-Heeger model
Xiao-Ming Wang, Shan-Zhong Li, Zhi Li
We study the topological properties of the one-dimensional generalized quasiperiodic modulated Su-Schrieffer-Heeger model. The results reveal that topological re-entrant phase tran…
Anderson-skin dualism: A boundary-dependent effect in non-Hermitian disordered coupled systems
Shan-Zhong Li, Linhu Li, Shi-Liang Zhu +1
We report a novel localization phenomenon that emerges in non-Hermitian and quasiperiodic coupled systems, which we dub ``Anderson-Skin (AS) dualism". The emergence of AS dualism i…
Multifractal-enriched mobility edges and emergent quantum phases in Rydberg atomic arrays
Shan-Zhong Li, Yi-Cai Zhang, Yucheng Wang +3
Anderson localization describes disorder-induced phase transitions, distinguishing between localized and extended states. In quasiperiodic systems, a third multifractal state emerg…
Emergent multi-loop nested point gap in a non-Hermitian quasiperiodic lattice
Yi-Qi Zheng, Shan-Zhong Li, Zhi Li
We propose a geometric series modulated non-Hermitian quasiperiodic lattice model, and explore its localization and topological properties. The results show that with the ever-incr…
Exact mobility line and mobility ring in the complex energy plane of a flat band lattice with a non-Hermitian quasiperiodic potential
Guang-Xin Pang, Zhi Li, Shan-Zhong Li +3
In this study, we investigate the problem of Anderson localization in a one-dimensional flat band lattice with a non-Hermitian quasiperiodic on-site potential. First of all, we dis…
