Aharonov-Bohm Caging and Inverse Anderson transition in Ultracold Atoms
Hang Li, Zhaoli Dong, Stefano Longhi +3
Aharonov-Bohm (AB) caging, a special flat-band localization mechanism, has spurred great interest in different areas of physics. AB caging can be harnessed to explore the rich and…
Observation of Non-Hermitian Skin Effect and Topology in Ultracold Atoms
Qian Liang, Dizhou Xie, Zhaoli Dong +5
The non-Hermitian skin effect (NHSE), the accumulation of eigen wavefunctions at boundaries of open systems, underlies a variety of exotic properties that defy conventional wisdom.…
A Gross-Pitaevskii-equation description of the momentum-state lattice: roles of the trap and many-body interactions
Tao Chen, Dizhou Xie, Bryce Gadway +1
We report a theoretical description of the synthetic momentum-state lattices with a 3D Gross-Pitaevskii equation (GPE), where both the external trap potential and the mean-field sp…
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…
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…
An in-situ method for measuring the non-linear response of a Fabry-Perot cavity
Wenhao Bu, Mengke Liu, Dizhou Xie +1
High finesse Fabry-Perot(FP) cavity is a very important frequency reference for laser stabiliza- tion, and is widely used for applications such as precision measurement, laser cool…
