Finite size effects on the collective oscillations of a trapped Bose gas
Francesca Zambelli, Sandro Stringari
Sum rules are used to calculate the corrections to the hydrodynamic collective frequencies of a harmonically trapped Bose gas at T=0, due to finite size effects. We show that, with…

Vortex nucleation and quadrupole deformation of a rotating Bose-Einstein condensate
M. Kraemer, L. Pitaevskii, S. Stringari +1
Using a semi-analytic model based on the Thomas-Fermi approximation, we investigate the relevance of the quadrupole deformation of a trapped Bose-Einstein condensate for the nuclea…
