Stable real-energy spectral dynamics with topological transitions and non-Hermitian many-body localization
Shujie Cheng, Xixi Feng, Wen Chen +2
In this work, the interplay between non-Hermiticity, quasi-disorder, and repulsive interaction is studied for hard-core bosons confined in a one-dimensional optical lattice, where…

Power law hopping of single particles in one-dimensional non-Hermitian quasicrystals
Dechi Peng, Shujie Cheng, Gao Xianlong
In this paper, a non-Hermitian Aubry-André-Harper model with power-law hoppings () and quasiperiodic parameter is studied, where is the power-law index, is the…

From topological phase to Anderson localization in a two-dimensional quasiperiodic system
Shujie Cheng, Reza Asgari, Gao Xianlong
In this paper, the influence of the quasidisorder on a two-dimensional system is studied. We find that there exists a topological phase transition accompanied by a transverse Ander…
