Homogeneous fermionic Hubbard gases in a flat-top optical lattice
Yu-Xuan Wang, Hou-Ji Shao, Yan-Song Zhu +6
Fermionic atoms in a large-scale, homogeneous optical lattice provide an ideal quantum simulator for investigating the fermionic Hubbard model, yet achieving this remains challengi…
Observation of the antiferromagnetic phase transition in the fermionic Hubbard model
Hou-Ji Shao, Yu-Xuan Wang, De-Zhi Zhu +9
The fermionic Hubbard model (FHM)[1], despite its simple form, captures essential features of strongly correlated electron physics. Ultracold fermions in optical lattices[2, 3] pro…
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…
A 30 W, sub-kHz frequency-locked laser at 532 nm
Hao-Ze Chen, Xiang-Pei Liu, Xiao-Qiong Wang +5
We report on the realization of a high-power, ultranarrow-linewidth, and frequency-locked 532~nm laser system. The laser system consists of single-pass and intra-cavity second harm…
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
Yu-Ping Wu, Xing-Can Yao, Xiang-Pei Liu +6
Recent experimental realizations of superfluid mixtures of Bose and Fermi quantum gases provide a unique platform for exploring diverse superfluid phenomena. We study dipole oscill…
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…
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…
