Tunable non-Hermitian skin effect and topological phases in ladders with staggered nonreciprocal inter-leg hopping
Pu-Xuan Li, Qi-Bo Zeng
We investigate the non-Hermitian skin effect (NHSE) and topological phases in a ladder model with staggered nonreciprocal inter-leg hopping, consisting of an Su-Schrieffer-Heeger (…
Topological phase and its effective tuning in a ladder lattice
Qi-Bo Zeng
We study a two-leg ladder model consists of a one-dimensional (1D) Su-Schrieffer-Heeger (SSH) lattice with staggered nearest-neighboring hopping amplitudes and a normal 1D tight-bi…
Topological Anderson insulators and reentrant topological transitions in a quasiperiodic long-range Su-Schrieffer-Heeger model
Fang-Ming Meng, Qi-Bo Zeng
We study a one-dimensional long-range Su-Schrieffer-Heeger model with third-nearest-neighbor hopping and subject to quasiperiodic disorder. In the clean limit, the model hosts phas…
Coexistence of topological Anderson insulator and multifractal critical phase in a non-Hermitian quasicrystal
Qi-Bo Zeng, Rong Lü
The interplay of topology, disorder, and non-Hermiticity gives rise to phenomena beyond the conventional classification of quantum phases. We propose a one-dimensional non-Hermitia…
Topological superconducting phase in a non-Hermitian Kitaev chain with staggered pairing imbalance
Xiao-Jue Zhang, Rong Lü, Qi-Bo Zeng
We introduce a one-dimensional non-Hermitian Kitaev chain with staggered imbalance in the -wave superconducting pairing. By tuning the chemical potential and the pairing imbalan…
Majorana edge modes in one-dimensional Kitaev chain with staggered -wave superconducting pairing
Xiao-Jue Zhang, Rong Lü, Qi-Bo Zeng
We introduce a new type of one-dimensional Kitaev chain with staggered -wave superconducting pairing. We find three physical regimes in this model by tuning the -wave pairing…
Investigation of reentrant localization transition in one-dimensional quasi-periodic lattice with long-range hopping
Pei-Jie Chang, Qi-Bo Zeng, Jinghui Pi +2
Reentrant localization has recently been observed in systems with quasi-periodic nearest-neighbor hopping, where the interplay between dimerized hopping and staggered disorder is i…
Coexistence of non-Hermitian skin effect and extended states in one-dimensional nonreciprocal lattices
Han Xiao, Qi-Bo Zeng
We study the one-dimensional non-Hermitian lattices with staggered onsite modulations and nonreciprocal hopping up to the next-nearest-neighboring (NNN) sites. Due to the NNN nonre…
Dissolution of the non-Hermitian skin effect in one-dimensional lattices with linearly varying nonreciprocal hopping
Bo Hou, Han Xiao, Rong Lü +1
We study the one-dimensional non-Hermitian lattices with linearly varying nonreciprocal hopping, where the non-Hermitian skin effect (NHSE) is found to be dissolved gradually as th…
