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…
Quantum Zeno effects across a parity-time symmetry breaking transition in atomic momentum space
Tao Chen, Wei Gou, Dizhou Xie +4
We experimentally study quantum Zeno effects in a parity-time (PT) symmetric cold atom gas periodically coupled to a reservoir. Based on the state-of-the-art control of inter-site…
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…
