Polarons in a ferromagnetic spinor Bose-Einstein condensates
Xiao-Lu Yu, Boyang Liu
We investigate the polarons formed by immersing a spinor impurity in a ferromagnetic state of spinor Bose-Einstein condensate. The ground state energies and effective masses…
Collective modes of spin-orbit coupled Fermi gases in the repulsive regime
Shang-Shun Zhang, Xiao-Lu Yu, Jinwu Ye +1
We investigate the collective modes in the spin-orbit coupled Fermi gas with repulsive s-wave interaction. The interplay between spin-orbit coupling and atom-atom interactions play…
Normal state properties of spin-orbit coupled Fermi gases in the upper branch of energy spectrum
Xiao-Lu Yu, Shang-Shun Zhang, Wu-Ming Liu
We investigate normal state properties of spin-orbit coupled Fermi gases with repulsive s-wave interaction, in the absence of molecule formation, i.e., in the so-called "upper bran…
Renormalization group analysis of -orbital Bose-Einstein condensates in a square optical lattice
Boyang Liu, Xiao-Lu Yu, Wu-Ming Liu
We investigate the quantum fluctuation effects in the vicinity of the critical point of a -orbital bosonic system in a square optical lattice using Wilsonian renormalization gro…
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…
