Dynamic structure factor of a Bose Einstein condensate in a 1D optical lattice
C. Menotti, M. Kraemer, L. Pitaevskii +1
We study the effect of a one dimensional periodic potential on the dynamic structure factor of an interacting Bose Einstein condensate at zero temperature. We show that, due to pho…
Macroscopic dynamics of a Bose-Einstein condensate containing a vortex lattice
Marco Cozzini, Sandro Stringari
Starting from the equations of rotational hydrodynamics we study the macroscopic behaviour of a trapped Bose-Einstein condensate containing a large number of vortices. The stationa…
Scissors mode of a rotating Bose-Einstein condensate
Marco Cozzini, Sandro Stringari, Vincent Bretin +2
A scissors mode of a rotating Bose-Einstein condensate is investigated both theoretically and experimentally. The condensate is confined in an axi-symmetric harmonic trap, superimp…
