Pair correlations of an expanding superfluid Fermi gas
C. Lobo, I. Carusotto, S. Giorgini +2
The pair correlation function of an expanding gas is investigated with an emphasis on the BEC-BCS crossover of a superfluid Fermi gas at zero temperature. At unitarity quantum Mont…
Beyond Tonks-Girardeau: strongly correlated regime in quasi-one-dimensional Bose gases
G. E. Astrakharchik, J. Boronat, J. Casulleras +1
We consider a homogeneous 1D Bose gas with contact interactions and large attractive coupling constant. This system can be realized in tight waveguides by exploiting a confinement…
Interacting fermions in quasi-one-dimensional harmonic traps
G. E. Astrakharchik, D. Blume, S. Giorgini +1
Quasi-one-dimensional (quasi-1d) two-component Fermi gases with effectively attractive and repulsive interactions are characterized for arbitrary interaction strength. The ground-s…
Quasi-one-dimensional Bose gases with large scattering length
G. E. Astrakharchik, D. Blume, S. Giorgini +1
Bose gases confined in highly-elongated harmonic traps are investigated over a wide range of interaction strengths using quantum Monte Carlo techniques. We find that the properties…
