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…
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…
