BCS-BEC crossover in a trapped Fermi super-fluid using a density-functional equation
(Iop Publishing Ltd, 2010-04-28)
We derive a generalized time-dependent Galilean-invariant density-functional (DF) equation appropriate to study the stationary and non-stationary properties of a trapped Fermi super-fluid in the Bardeen-Cooper-Schrieffer ...

BEC-BCS crossover in a cold and magnetized two color NJL model
(American Physical Society, 2016-01)
The BEC-BCS crossover for a Nambu-Jona-Lasinio (NJL) model with diquark interactions is studied in the presence of an external magnetic field. Particular attention is paid to different regularization schemesused in the ...
The BCS-Bose crossover theory
(Elsevier B.V., 2007-03-15)
We contrast four distinct versions of the BCS-Bose statistical crossover theory according to the form assumed for the electron-number equation that accompanies the BCS gap equation. The four versions correspond to explicitly ...

Nonlinear Schrodinger equation for a superfluid Fermi gas in the BCS-BEC crossover
(Amer Physical Soc, 2008-04-01)
We introduce a quasianalytic nonlinear Schrodinger equation with beyond mean-field corrections to describe the dynamics of a zero-temperature dilute superfluid Fermi gas in the crossover from the weak-coupling Bardeen-Co ...

A strongly attractive Fermi gas in an optical lattice
(ELSEVIER SCIENCE BV, 2010)
We study strongly attractive fermions in an optical lattice superimposed by a trapping potential. We calculate the densities of fermions and condensed bound molecules at zero temperature. There is a competition between ...
