Half-vortex sheets and domain-wall trains of rotating two-component Bose-Einstein condensates in spin-dependent optical lattices
Wei Han, Suying Zhang, Jingjing Jin +1
We investigate half-vortex sheets and domain-wall trains of rotating two-component Bose-Einstein condensates in spin-dependent optical lattices. The two-component condensates under…
Crystallized merons and inverted merons in the condensation of spin-1 Bose gases with spin-orbit coupling
S. -W. Su, I. -K. Liu, Y. -C. Tsai +2
The non-equilibrium dynamics of a rapidly quenched spin-1 Bose gas with spin-orbit coupling is studied. By solving the stochastic projected Gross-Pitaevskii equation, we show that…
Optomechanically-Based Probing of Spin-Charge Separation in Ultracold Gases
Qing Sun, W. M. Liu, An-Chun Ji
We propose a new approach to investigate the spin-charge separation in 1D quantum liquids via the optomechanical coupled atom-cavity system. We show that, one can realize an effect…
Wigner crystal induced by dipole-dipole interaction in one-dimensional optical lattices
Zhihao Xu, Shu Chen
We demonstrate that the static structure factor, momentum distribution and density distribution provide clear signatures of the emergence of Wigner crystal for the fermionic dipola…
Topological Quantum Phase Transition in Synthetic Non-Abelian Gauge Potential
Fadi Sun, Xiao-Lu Yu, Jinwu Ye +2
The method of synthetic gauge potentials opens up a new avenue for our understanding and discovering novel quantum states of matter. We investigate the topological quantum phase tr…
Imbalanced ultracold Fermi gas in the weakly repulsive regime: Renormalization group approach for p-wave superfluidity
Shao-Jian Jiang, Xiao-Lu Yu, W. M. Liu
We theoretically study a possible new pairing mechanism for a two-dimensional population imbalanced Fermi gas with short-range repulsive interactions which can be realized on the u…
