Transport measurement of fractional charges in topological models
Shu-guang Cheng, Yijia Wu, Hua Jiang +2
The static topological fractional charge (TFC) in condensed matter systems is related to the band topology and thus has potential applications in topological quantum computation. H…
Mobility edges in -symmetric cross-stitch flat band lattices
Tong Liu, Shujie Cheng
We study the cross-stitch flat band lattice with a -symmetric on-site potential and uncover mobility edges with exact solutions. Furthermore, we study the relationshi…
Majorana zero modes, unconventional real-complex transition and mobility edges in a one-dimensional non-Hermitian quasi-periodic lattice
Shujie Cheng, Gao Xianlong
In this paper, a one-dimensional non-Hermitian quasiperiodic -wave superconductor without -symmetry is studied. By analyzing the spectrum, we discovered there stil…
Invariable mobility edge in a quasiperiodic lattice
Tong Liu, Yufei Zhu, Shujie Cheng +3
In this paper, we study a one-dimensional tight-binding model with tunable incommensurate potentials. Through the analysis of the inverse participation rate, we uncover that the wa…
Fate of Majorana zero modes, critical states and non-conventional real-complex transition in non-Hermitian quasiperiodic lattices
Tong Liu, Shujie Cheng, Hao Guo +1
We study a one-dimensional -wave superconductor subject to non-Hermitian quasiperiodic potentials. Although the existence of the non-Hermiticity, the Majorana zero mode is still…
Large Chern numbers in a dissipative dice model
Shujie Cheng, Gao Xianlong
For decades, the topological phenomena in quantum systems have always been catching our attention. Recently, there are many interests on the systems where topologically protected e…
