Axial collective excitations of a degenerate Fermi gas in the BEC to unitarity crossover
R. Combescot, X. Leyronas
We show that, with reasonable hypotheses leading to a simple modeling,a link can be obtained from experiments on the axial low frequency collective modes between the molecular scat…
Comment on "Collective excitations of a degenerate gas at the BEC-BCS crossover"
R. Combescot, X. Leyronas
Very recent experiments have studied for the first time collective excitations of an ultracold Li gas covering in particular the BEC-BCS crossover domain. We point out that the…
Hydrodynamic modes of a 1D trapped Bose gas
J. N. Fuchs, X. Leyronas, R. Combescot
We consider two regimes where a trapped Bose gas behaves as a one-dimensional system. In the first one the Bose gas is microscopically described by 3D mean field theory, but the tr…
Hydrodynamic modes in dense trapped ultracold gases
R. Combescot, X. Leyronas
We consider the hydrodynamic modes for dense trapped ultracold gases, where the interparticle distance is comparable to the scattering length. We show that the experimental determi…
