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…
Fate of pseudo mobility-edge and multiple states in non-Hermitian Wannier-Stark lattice
Yu-Jun Zhao, Han-Ze Li, Xuyang Huang +2
The interaction between non-reciprocity and disorder-free localization has emerged as a fascinating open question. Here, we explore the effects of pseudo mobility edges (MEs) along…
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…
