Equation of state of a superfluid Fermi gas in the BCS-BEC crossover
- Hui Hu, Xia-ji Liu, P. Drummond
- Physics
- 2 June 2005
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 Schmitt-Rink for…
Virial expansion for a strongly correlated Fermi gas.
- Xia-ji Liu, Hui Hu, P. Drummond
- Physics
- 31 March 2009
Using a high temperature virial expansion, we present a controllable study of the thermodynamics of strongly correlated Fermi gases near the BEC-BCS crossover region. We propose a practical way to…
Quantum fluctuations in the BCS-BEC crossover of two-dimensional Fermi gases
- Lianyi He, Haifeng Lv, Gaoqing Cao, Hui Hu, Xia-ji Liu
- Physics
- 23 June 2015
We present a theoretical study of the ground state of the BCS-BEC crossover in dilute two-dimensional Fermi gases. While the mean-field theory provides a simple and analytical equation of state, the…
Ultra-cold Fermi gases
- Xia-ji Liu, P. Drummond, Hui Hu
- Physics
- 2005
Molecule formation in ultracold degenerate quantum gases is one of the central topics in the overall ACQAO program, due to the strong quantum correlations in these systems. An experimental program in…

A one-dimensional liquid of fermions with tunable spin
- G. Pagano, M. Mancini, L. Fallani
- Physics
- 1 March 2014
The physics of one-dimensional many-body systems is rich but still insufficiently understood. An ultracold atom experiment investigates the behaviour of one-dimensional strongly correlated fermions…
Universal contact of strongly interacting fermions at finite temperatures
- Hui Hu, Xia-ji Liu, P. Drummond
- Physics
- 16 November 2010
The recently discovered universal thermodynamic behavior of dilute, strongly interacting Fermi gases also implies a universal structure in the many-body pair-correlation function at short distances,…
Anderson localization transition in a robust
PT
-symmetric phase of a generalized Aubry-André model
- S. Schiffer, Xia-ji Liu, Hui Hu, Jia Wang
- Physics
- 29 January 2021
We study a generalized Aubry-Andr\'e model that obeys $\mathcal{PT}$ symmetry. We observe a robust $\mathcal{PT}$-symmetric phase with respect to system size and disorder strength, where all…
Finite-momentum dimer bound state in a spin-orbit-coupled Fermi gas
- Lin Dong, Leidi Jiang, Hui Hu, H. Pu
- Physics
- 7 November 2012
We investigate the two-body properties of a spin-1/2 Fermi gas subject to a spin-orbit coupling induced by laser fields. When an attractive s-wave interaction between unlike spins is present, the…
Aharonov-Bohm effect of excitons in nanorings
- Hui Hu, Jia-lin Zhu, Dai-Jun Li, J. Xiong
- Physics
- 20 October 2000
The magnetic field effects on excitons in an InAs nano-ring are studied theoretically. By numerically diagonalizing the effective-mass Hamiltonian of the problem, which can be separated into terms in…
