Excitation spectroscopy of vortex lattices in a rotating Bose-Einstein condensate
arXiv:cond-mat/0308431 · doi:10.1103/PhysRevLett.92.170402
Abstract
Excitation spectroscopy of vortex lattices in rotating Bose-Einstein condensates is described. We numerically obtain the Bogoliubov-deGenne quasiparticle excitations for a broad range of energies and analyze them in the context of the complex dynamics of the system. Our work is carried out in a regime in which standard hydrodynamic assumptions do not hold, and includes features not readily contained within existing treatments.
