Collective dynamics of vortices in trapped Bose-Einstein condensates
arXiv:1303.0947 · doi:10.1103/PhysRevA.87.023630
Abstract
We have calculated collective mode spectra for three-dimensional, rotating Bose-Einstein condensates in oblate harmonic traps using the microscopic Bogoliubov-deGennes field theory. For condensates with vortices, Kelvin-Tkachenko mode branches are obtained. The features of these modes are compared with those predicted by a classical point vortex model. We have created movies to visualize the motion of the vortices corresponding to the Kelvin-Tkachenko waves.
