Fractional Chern insulator with higher Chern number in optical lattice
Ying-Xing Ding, Wen-Tong Li, Li-Min Zhang +4
Fractional Chern insulators arise in topologically nontrivial flat bands, characterized by an integer Chern number C that corresponds to the number of dissipationless edge states i…

Detecting the entanglement of vortices in ultracold bosons with artificial gauge fields
Li Dai, Lin Xia, Lin Zhuang +1
The entanglement of vortices in a two-dimensional Bose-Hubbard model with artificial gauge fields is investigated using the exact diagonalization techniques. We propose an effectiv…

Tunable spinful matter wave valve
Yan-Jun Zhao, Dongyang Yu, Lin Zhuang +1
We investigate the transport problem that a spinful matter wave is incident on a strong localized spin-orbit-coupled Bose-Einstein condensate in optical lattices, where the localiz…
