Interaction-assisted topological pumping in few- and many-atom Rydberg arrays
Chenxi Huang, Tao Chen, Qian Liang +7
Topology can imbue lattice systems with special properties, notably the presence of robust eigenstates living at their boundary. Through dimensional reduction, the robust bulk band…
Interaction-induced chiral-transport inversion
Li Pan, Qian Liang, Chang-An Yang +6
We investigate the chiral dynamics of locally interacting bosons in a two-leg flux ladder, where on-site interactions, despite being fully isotropic, counterintuitively reverse the…
Chiral Dynamics of Ultracold Atoms under a Tunable SU(2) Synthetic Gauge Field
Qian Liang, Zhaoli Dong, Hongru Wang +5
Surface currents emerge in superconductors exposed to magnetic fields, and are a key signature of the Meissner effect. Analogously, chiral dynamics were observed in quantum simulat…
Engineering topological chiral transport in a flat-band lattice of ultracold atoms
Hang Li, Qian Liang, Zhaoli Dong +4
The manipulation of particle transport in synthetic quantum matter is an active research frontier for its theoretical importance and potential applications. Here we experimentally…
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…
Saturated absorption spectroscopy of buffer-gas-cooled Barium monofluoride molecules
Wenhao Bu, Yuhe Zhang, Qian Liang +2
We report an experimental investigation on the Doppler-free saturated absorption spectroscopy of buffer-gas-cooled Barium monofluoride (BaF) molecules in a 4~K cryogenic cell. The…
Doppler cooling of buffer-gas-cooled Barium monofluoride molecules
Yuhe Zhang, Zixuan Zeng, Qian Liang +2
We demonstrate one-dimensional Doppler cooling of a beam of buffer-gas cooled Barium monofluoride (BaF) molecules. The dependences of the cooling efficiency with the laser detuning…
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 general Zeeman slower for type-II transitions and polar molecules
Qian Liang, Wenhao Bu, Yuhe Zhang +2
We proposed a general Zeeman slower scheme applicable to the majority of the laser-coolable molecules. Different from previous schemes, the key idea of our scheme lies in that the…
Laser cooling with adiabatic passage for diatomic molecules
Qian Liang, Tao Chen, Wenhao Bu +2
We present a magnetically enhanced laser cooling scheme applicable to multi-level type-II transitions and further diatomic molecules with adiabatic transfer. An angled magnetic fie…
