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…

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…
