Comparative study of strong coupling theories of a trapped Fermi gas at unitarity
Hui Hu, Xia-Ji Liu, Peter D. Drummond
We present a systematic comparison of the most recent thermodynamic measurements of a trapped Fermi gas at unitarity with predictions from strong coupling theories and quantum Mont…
Finite temperature phase diagram of a spin-polarized ultracold Fermi gas in a highly elongated harmonic trap
Xia-Ji Liu, Hui Hu, Peter D. Drummond
We investigate the finite temperature properties of an ultracold atomic Fermi gas with spin population imbalance in a highly elongated harmonic trap. Previous studies at zero tempe…
Fulde-Ferrell-Larkin-Ovchinnikov states in one-dimensional spin-polarized ultracold atomic Fermi gases
Xia-Ji Liu, Hui Hu, Peter D. Drummond
We present a systematic study of quantum phases in a one-dimensional spin-polarized Fermi gas. Three comparative theoretical methods are used to explore the phase diagram at zero t…
BCS-BEC crossover in an asymmetric two-component Fermi gas
Xia-Ji Liu, Hui Hu
We discuss the superfluid phase transition of a strongly interacting Fermi gas with unequal (asymmetric) chemical potentials in two pairing hyperfine states, and map out its phase…
Signature of Mott-insulator transition with ultra-cold fermions in a one-dimensional optical lattice
Xia-Ji Liu, Peter D. Drummond, Hui Hu
Using the exact Bethe ansatz solution of the Hubbard model and Luttinger liquid theory, we investigate the density profiles and collective modes of one-dimensional ultra-cold fermi…
Collective modes and ballistic expansion of a Fermi gas in the BCS-BEC crossover
Hui Hu, A. Minguzzi, Xia-Ji Liu +1
We evaluate the frequencies of collective modes and the anisotropic expansion rate of a harmonically trapped Fermi superfluid at varying coupling strengths across a Feshbach resona…
Collective oscillations of a confined Bose gas at finite temperature in the random-phase approximation
Xia-Ji Liu, Hui Hu, A. Minguzzi +1
We present a theory for the linear dynamics of a weakly interacting Bose gas confined inside a harmonic trap at finite temperature. The theory treats the motions of the condensate…
Why only half of the fermionic atoms were converted to molecules by a Feshbach resonance?
Hui Hu, Feng Yuan, Shaojin Qin
In some recent experiments an ultracold gas of K (or Li) molecules has been produced from a degenerate two-component Fermi gas of K (or Li) atoms…
Finite temperature effects on the collapse of trapped Bose-Fermi mixtures
Xia-Ji Liu, Michele Modugno, Hui Hu
By using the self-consistent Hartree-Fock-Bogoliubov-Popov theory, we present a detailed study of the mean-field stability of spherically trapped Bose-Fermi mixtures at finite temp…
Thermodynamics of a Trapped Bose-Fermi Mixture
Hui Hu, Xia-Ji Liu
By using the Hartree-Fock-Bogoliubov equations within the Popov approximation, we investigate the thermodynamic properties of a dilute binary Bose-Fermi mixture confined in an isot…
Collisionless and hydrodynamic excitations of trapped boson-fermion mixtures
Xia-Ji Liu, Hui Hu
Within a scaling ansatz formalism plus Thomas-Fermi approximation, we investigate the collective excitations of a harmonically trapped boson-fermion mixture in the collisionless an…
Ground state properties of a trapped few-Boson system under rotation --beyond the "lowest Landau level" approximation--
Xiaji Liu, Hui Hu, Lee Chang +1
We consider a harmonically trapped few-Boson system under rotation and investigate the ground state properties beyond the usual ``lowest Landau level'' approximation by using exact…
Fragmented Condensate Ground State of Trapped Weakly Interacting Bosons in Two Dimensions
Xia-Ji Liu, Hui Hu, Lee Chang +3
The ground state and its structure for a rotating, harmonically trapped N-Boson system with a weak repulsive contact interaction are studied as the angular momentum L increases up…
Resonant quantum coherence of magnetization at excited states in nanospin systems with different crystal symmetries
Jia-Lin Zhu, Rong Lu, Su-Pen Kou +2
The quantum interference effects induced by the Wess-Zumino term, or Berry phase are studied theoretically in resonant quantum coherence of magnetization vector between degenerate…
