Dual-species Bose-Einstein condensates of Li and Cs
Y. -D. Chen, W. -X. Li, Y. -T. Sun +3
We report the creation of dual-species Bose-Einstein condensates (BECs) of Li and Cs. These BECs are formed in a bichromatic optical dipole trap created with 1550-nm…
Feshbach resonances in an ultracold Li-Cs Bose-Bose mixture
W. -X. Li, Y. -D. Chen, Y. -T. Sun +2
We present a study of interspecies Feshbach resonances in ultracold Li-Cs Bose-Bose mixtures. We locate ten interspecies resonances in three different spin-state comb…
Geometric scaling of Efimov states in a - mixture
Shih-Kuang Tung, Karina Jimenez-Garcia, Jacob Johansen +2
In few-body physics, Efimov states are an infinite series of three-body bound states that obey universal discrete scaling symmetry when pairwise interactions are resonantly enhance…
Strongly Interacting Two-Dimensional Bose Gases
Li-Chung Ha, Chen-Lung Hung, Xibo Zhang +3
We prepare and study strongly interacting two-dimensional Bose gases in the superfluid, the classical Berezinskii-Kosterlitz-Thouless (BKT) transition, and the vacuum-to-superfluid…
Ultracold mixtures of atomic Li-6 and Cs-133 with tunable interactions
Shih-Kuang Tung, Colin Parker, Jacob Johansen +3
We report the experimental and theoretical study of two-body interactions in a Li-Cs Fermi- Bose mixture. Using a translatable dipole trap setup, we have successfully…
Quantum critical behavior of ultracold atoms in two-dimensional optical lattices
Xibo Zhang, Chen-Lung Hung, Shih-Kuang Tung +1
As the temperature of a many-body system approaches absolute zero, thermal fluctuations of observables cease and quantum fluctuations dominate. Competition between different energi…
