Pseudopotential in resonant regimes

Author(s) : Pricoupenko, Ludovic
Description : The zero-range potential approach is extended for the description of situations where two-body scattering is resonant in arbitrary partial waves. The formalism generalizes the Fermi pseudopotential which can be used only for s-wave broad resonances. In a given channel, the interaction is described e...

Population and Phase Coherence during the Growth of an Elongated Bose-Einstein Condensate

Author(s) : Hugbart, Mathilde , Retter, Jocelyn A. , Varòn, Andrès , Bouyer, Philippe , Aspect, Alain , Davis, Matthew
Description : We study the growth of an elongated phase-fluctuating condensate from a non-equilibrium thermal cloud obtained by shock-cooling. We compare the growth of the condensate with numerical simulations, revealing a time delay and a reduction in the growth rate which we attribute to phase fluctuations. We ...
