Quantum time reflection and refraction of ultracold atoms
Zhaoli Dong, Hang Li, Tuo Wan +3
Time reflection and refraction are temporal analogies of the spatial boundary effects derived from Fermat's principle. They occur when classical waves strike a time boundary where…
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…
