2014/12/19
The strongly correlated regime of the crossover from Bardeen-Cooper-Schrieffer pairing to Bose-Einstein condensation can be realized by diluting a system of two-component fermions with a short-range a...

Abstract: We study the BCS gap equation for a Fermi gas with unequal population of spin-up and spin-down states. For $\cosh(\delta_\mu/T) \leq 2$, with $T$ the temperature and $\delta_\mu$ the chemica...

We show how multi-level BCS Hamiltonians of finite systems in the strong pairing interaction
regime can be accurately approximated using multi-dimensional shifted harmonic oscillator Hamil-tonians.
Population imbalance and pairing in the BCS-BEC crossover of three-component ultracold fermions

We investigate the phase diagram and the BCS-BEC crossover of a homogeneous three-component
ultracold Fermi gas with a U(3) invariant attractive interaction. We show that the system at
sufficiently ...

We investigate the crossover from Bardeen-Cooper-Schrieffer (BCS) superfluidity to Bose-Einstein condensation (BEC) in a two-dimensional Fermi gas at T = 0 using the fixed-node diffusion Monte Carlo m...
Finite dimensional global and exponential attractors for a coupled time-dependent Ginzburg-Landau equations for atomic Fermi gases near the BCS-BEC crossover
Finite dimensional global exponential attractors
font style='font-size:12px;'>
2010/11/9
We study a coupled nonlinear evolution system arising from the Ginzburg-Landau theory for atomic Fermi gases near the BCS-BEC crossover. First, we prove that the initial boundary value problem genera...

Unified BCS-like model of pairing alpha-correlations
font style='font-size:12px;'>
2011/1/7
We construct a BCS-like model that combines nucleonic pairing cor-relations and possible quartic correlations of alpha-type in a single vari-ational wave function and derive corresponding gap equation...
