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…
Momentum transferred to a trapped Bose-Einstein condensate by stimulated light scattering
A. Brunello, F. Dalfovo, L. Pitaevskii +2
The response of a trapped Bose-Einstein condensed gas to a density perturbation generated by a two-photon Bragg pulse is investigated by solving the time-dependent Gross-Pitaevskii…
Overcritical Rotation of a Trapped Bose-Einstein Condensate
A. Recati, F. Zambelli, S. Stringari
The rotational motion of an interacting Bose-Einstein condensate confined by a harmonic trap is investigated by solving the hydrodynamic equations of superfluids, with the irrotati…
Moment of Inertia and Quadrupole Response Function of a Trapped Superfluid
Francesca Zambelli, Sandro Stringari
We derive an explicit relationship between the moment of inertia and the quadrupole response function of an interacting gas confined in a harmonic trap. The relationship holds for…
Dynamic structure factor and momentum distribution of a trapped Bose gas
F. Zambelli, L. P. Pitaevskii, D. M. Stamper-Kurn +1
The dynamic structure factor of a trapped Bose-Einstein condensed gas is investigated at zero temperature in the framework of Bogoliubov theory. Different values of momentum transf…
