Hidden Unbounded Potential and Re-Entrant Multifractalization in a Generalized Su-Schrieffer-Heeger Model
Yun-Yan Chen, Jia-Ming Zhang, Zhi Li
We study the multifractal criticality in a generalized Su-Schrieffer-Heeger model. The results show that the system supports not only critical phases but also re-entrance multifrac…
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…
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…
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…
Emergent extended states in an unbounded quasiperiodic lattice
Jia-Ming Zhang, Shan-Zhong Li, Shi-Liang Zhu +1
Previous studies have established that quasiperiodic lattice models with unbounded potentials can exhibit localized and multifractal states, yet preclude the existence of extended…
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 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…
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…
Asymmetric transfer matrix analysis of Lyapunov exponents in one-dimensional non-reciprocal quasicrystals
Shan-Zhong Li, Enhong Cheng, Shi-Liang Zhu +1
The Lyapunov exponent, serving as an indicator of the localized state, is commonly utilized to identify localization transitions in disordered systems. In non-Hermitian quasicrysta…
Ring Structure in the Complex Plane: A Fingerprint of non-Hermitian Mobility Edge
Shan-Zhong Li, Zhi Li
By Avila's global theory, we analytically reveal that the non-Hermitian mobility edge will take on a ring structure in the complex plane, which we name as "mobility ring". The univ…
Emergent strength-dependent scale-free mobility edge in a non-reciprocal long-range Aubry-André-Harper model
Gui-Juan Liu, Jia-Ming Zhang, Shan-Zhong Li +1
We investigate the properties of mobility edge in an Aubry-André-Harper model with non-reciprocal long-range hopping. The results reveal that there can be a new type of mobility ed…
Emergent entanglement phase transitions in non-Hermitian Aubry-André-Harper chains
Shan-Zhong Li, Xue-Jia Yu, Zhi Li
We investigate the entanglement dynamics of the non-Hermitian Aubry-André-Harper (AAH) chain. The results reveal that by increasing quasiperiodic strength, a phase transition occur…
The multiple re-entrant localization in a phase-shift quasiperiodic chain
Shan-Zhong Li, Zhi Li
Inspired by the recently discovered phenomenon of re-entrant localization (REL) [Roy et al., PRL 126, 106803 (2021)], we propose a new approach to induce REL, i.e., to control the…
Emergent Recurrent Extension Phase Transition in a Quasiperiodic Chain
Shan-Zhong Li, Zhi Li
We study -wave superconducting quasiperiodic chains with staggered potential. The result shows a counter-intuitive phase transition phenomenon, i.e., recurrent extension phase t…
