Equation of state of a superfluid Fermi gas in the BCS-BEC crossover
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.
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
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
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
Virial expansion for a strongly correlated Fermi gas.
Using a high temperature virial expansion, this work proposes a practical way to determine the expansion coefficients for both harmonically trapped and homogeneous cases, and calculates the third order coefficient b{3}(T) at finite temperatures T.
A one-dimensional liquid of fermions with tunable spin
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
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
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
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
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
