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…
Comment on "Floquet topological phase transition in the -- lattice"
Shujie Cheng
A recent paper studied the topological phase transition driven by the circular frequency light in the -- lattice. In this Comment we point out that there is a f…
Breakdown of the correspondence between the real-complex and delocalization-localization transitions in non-Hermitian quasicrystals
Wen Chen, Shujie Cheng, Ji Lin +2
The correspondence between the real-complex transition in energy and delocalization-localization transition is well-established in a class of Aubry-Andr'e-Harper model with exponen…
Topological Floquet-bands in a circularly shaken dice lattice
Shujie Cheng, Gao Xianlong
The hoppings of non-interacting particles in the optical dice lattice result in the gapless dispersions in the band structure formed by the three lowest minibands. In our research,…
