The Boltzmann equation for driven systems of inelastic soft spheres

M. H. Ernst, E. Trizac, A. Barrat

We study a generic class of inelastic soft sphere models with a binary collision rate that depends on the relative velocity . This includes previously studied inelastic ha…

The rich behavior of the Boltzmann equation for dissipative gases

M. H. Ernst, E. Trizac, A. Barrat

Within the framework of the homogeneous non-linear Boltzmann equation, we present a new analytic method, without the intrinsic limitations of existing methods, for obtaining asympt…

Bogoliubov theory of Feshbach molecules in the BEC-BCS crossover

M. W. J. Romans, H. T. C. Stoof

We present the Bogoliubov theory for the Bose-Einstein condensation of Feshbach molecules in a balanced Fermi mixture. Because the Bogoliubov theory includes (Gaussian) fluctuation…

FFLO Vortex Lattice States in Cold Fermionic-Atom Systems

Y. -P. Shim, R. A. Duine, A. H. MacDonald

Condensation of atom pairs with finite total momentum is expected in a portion of the phase diagram of a two-component fermionic cold-atom system. This unusual condensate can be id…

Sarma Phase in Trapped Unbalanced Fermi Gases

K. B. Gubbels, M. W. J. Romans, H. T. C. Stoof

We consider a trapped unbalanced Fermi gas at nonzero temperatures where the superfluid Sarma phase is stable. We determine in particular the phase boundaries between the superflui…

Dressed molecules in an optical lattice

K. B. Gubbels, D. B. M. Dickerscheid, H. T. C. Stoof

We present the theory of an atomic gas in an optical lattice near a Feshbach resonance. We derive from first principles a generalized Hubbard model, that incorporates all the relev…

BEC-BCS crossover in an optical lattice

Arnaud Koetsier, D. B. M. Dickerscheid, H. T. C. Stoof

We present the microscopic theory for the BEC-BCS crossover of an atomic Fermi gas in an optical lattice, showing that the Feshbach resonance underlying the crossover in principle…

Squeezing in the weakly interacting uniform Bose condensate

Masudul Haque, Andrei E. Ruckenstein

We investigate the presence of squeezing in the weakly repulsive uniform Bose gas, in both the condensate mode and in the nonzero opposite-momenta mode pairs, using two different v…
