Giant vortices in combined harmonic and quartic traps
Amandine Aftalion, Ionut Danaila
We consider a rotating Bose-Einstein condensate confined in combined harmonic and quartic traps, following recent experiments [V. Bretin, S. Stock, Y. Seurin and J. Dalibard, cond-…

Three-dimensional vortex configurations in a rotating Bose Einstein condensate
Amandine Aftalion, Ionut Danaila
We consider a rotating Bose-Einstein condensate in a harmonic trap and investigate numerically the behavior of the wave function which solves the Gross Pitaevskii equation. Followi…

Dissipative flow and vortex shedding in the Painlevé boundary layer of a Bose Einstein condensate
Amandine Aftalion, Qiang Du, Yves Pomeau
Raman et al. have found experimental evidence for a critical velocity under which there is no dissipation when a detuned laser beam is moved in a Bose-Einstein condensate. We analy…
