Temperature of a trapped unitary Fermi gas at finite entropy
Hui Hu, Xia-Ji Liu, Peter D. Drummond
We present theoretical predictions for the equation of state of a harmonically-trapped Fermi gas in the unitary limit. Our calculations rest on a study of the equation of state of…
Equation of state of a superfluid Fermi gas in the BCS-BEC crossover
Hui Hu, Xia-Ji Liu, Peter D. Drummond
We present a theory for a superfluid Fermi gas near the BCS-BEC crossover, including pairing fluctuation contributions to the free energy similar to that considered by Nozieres and…
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…
