Query: Collective dynamics of vortices in trapped Bose-Einstein condensates   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 $N_v$ vortices, $N_v$
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.
