Vortex oscillations in confined Bose-Einstein condensate interacting with 1D optical lattice
arXiv:cond-mat/0503509 · doi:10.1143/JPSJ.74.2764
Abstract
We study Bose-Einstein condensate of atomic Boson gases trapped in a composite potential of a harmonic potential and an optical lattice potential. We found a series of collective excitations that induces localized vortex oscillations with a characteristic wavelength. The oscillations might be observed experimentally when radial confinement is tight. We present the excitation spectra of the vortex oscillation modes and propose a way to experimentally excite the modes.
