Impurity induced quantum chaos for an ultracold bosonic ensemble in a double-well
Jie Chen, Kevin Keiler, Gao Xianlong +1
We demonstrate that an ultracold many-body bosonic ensemble confined in a one-dimensional (1D) double-well (DW) potential can exhibit chaotic dynamics due to the presence of a sing…
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…
Metal-insulator phase transition and topology in a three-component system
Shujie Cheng, Gao Xianlong
In the framework of the tight binding approximation, we study a non-interacting model on the three-component dice lattice with real nearest-neighbor and complex next-nearest-neighb…
Predicting Large-Chern-Number Phases in a Shaken Optical Dice Lattice
Shujie Cheng, Honghao Yin, Zhanpeng Lu +3
With respect to the quantum anomalous Hall effect (QAHE), the detection of topological nontrivial large-Chern-number phases is an intriguing subject. Motivated by recent research o…
Characterization of many-body mobility edges with random matrices
Xingbo Wei, Rubem Mondaini, Gao Xianlong
Whether the many-body mobility edges can exist in a one-dimensional interacting quantum system is a controversial problem, mainly hampered by the limited system sizes amenable to n…
