Observation of topological phase with critical localization in a quasi-periodic lattice
Teng Xiao, Dizhou Xie, Zhaoli Dong +3
Disorder and localization have dramatic influence on the topological properties of a quantum system. While strong disorder can close the band gap thus depriving topological materia…
Periodic driving induced helical Floquet channels with ultracold atoms in momentum space
Teng Xiao, Dizhou Xie, Wei Gou +4
Employing the external degrees of freedom of atoms as synthetic dimensions renders easy and new accesses to quantum engineering and quantum simulation. As a recent development, ult…
Tunable non-reciprocal quantum transport through a dissipative Aharonov-Bohm ring in ultracold atoms
Wei Gou, Tao Chen, Dizhou Xie +5
We report the experimental observation of tunable, non-reciprocal quantum transport of a Bose-Einstein condensate in a momentum lattice. By implementing a dissipative Aharonov-Bohm…
Topological characterizations of an extended Su-Schrieffer-Heeger model
Dizhou Xie, Wei Gou, Teng Xiao +2
The Su-Schrieffer-Heeger (SSH) model perhaps is the easiest and the most basic model for topological excitations. Many variations and extensions of the SSH model have been proposed…
Topological quantum walks in momentum space with a Bose-Einstein condensate
Dizhou Xie, Tian-Shu Deng, Teng Xiao +4
We report the experimental implementation of discrete-time topological quantum walks of a Bose-Einstein condensate in momentum space. Introducing stroboscopic driving sequences to…
