Observation of state-to-state hyperfine-changing collision in a Bose-Fermi mixture of Li and K atoms
Xiao-Qiong Wang, Yu-Xuan Wang, Xiang-Pei Liu +4
Hyperfine-changing collisions are of fundamental interest for the studying of ultracold heteronuclear mixtures. Here, we report the state-to-state study of the hyperfine-changing-c…
Feshbach spectroscopy of an ultracold K-Li mixture and K atoms
Xiang-Pei Liu, Xing-Can Yao, Ran Qi +4
We have observed 69 K-Li interspecies Feshbach resonances including 13 elastic p-wave resonances and 6 broad d-wave resonances of K atoms in different spin-state…
Observation of the density dependence of the closed-channel fraction of a Li superfluid
Xiang-Pei Liu, Xing-Can Yao, Hao-Ze Chen +6
Atomic Fermi gases provide an ideal platform for studying the pairing and superfluid physics, using a Feshbach resonance between closed channel molecular states and open channel sc…
Dynamic formation of quasicondensate and spontaneous vortices in a strongly interacting Fermi gas
Xiang-Pei Liu, Xing-Can Yao, Youjin Deng +6
We report an experimental study of quench dynamics across the superfluid transition temperature in a strongly interacting Fermi gas by ramping down the trapping potential. Th…
Strongly Interacting Bose Gases near a -wave Shape Resonance
Xing-Can Yao, Ran Qi, Xiang-Pei Liu +8
Many unconventional quantum matters, such as fractional quantum Hall effect and -wave high-Tc superconductor, are discovered in strongly interacting systems. Understanding quant…
Coupled Dipole Oscillations of a Mass-Imbalanced Bose and Fermi Superfluid Mixture

Oscillatory-like Expansion of a Fermionic Superfluid
Xiao-Qiong Wang, Yu-Ping Wu, Xiang-Pei Liu +7
We study the expansion behaviours of a Fermionic superfluid in a cigar-shaped optical dipole trap for the whole BEC-BCS crossover and various temperatures. At low temperature ($0.0…
Narrow-linewidth cooling of Li atoms using the 2S-3P transition
Hao-Ze Chen, Xing-Can Yao, Yu-Ping Wu +4
We report on a narrow-linewidth cooling of Li atoms using the transition in the ultraviolet (UV) wavelength regime. By combining the traditional red ma…
Production of large K Bose-Einstein condensates using D1 gray molasses
Hao-Ze Chen, Xing-Can Yao, Yu-Ping Wu +5
We use D1 gray molasses to achieve Bose-Einstein condensation of a large number of K atoms in an optical dipole trap. By combining a new configuration of compressed-MOT with…
Observation of two-species vortex lattices in a mixture of mass-imbalance Bose and Fermi superfluids
Xing-Can Yao, Hao-Ze Chen, Yu-Ping Wu +6
The superfluid mixture of interacting Bose and Fermi species is a remarkable many-body quantum system. Dilute degenerate atomic gases, especially for two species of distinct masses…
