Quadrupole Oscillation of a Single-Vortex Condensate: Evidence for Kelvin Modes
V. Bretin, P. Rosenbusch, F. Chevy +2
We study the two transverse quadrupole modes of a cigar-shaped Bose-Einstein condensate with a single centered vortex. We show that the counter-rotating mode is more strongly dampe…

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…
