Phys. Rev. A 68, 033611 (2003) [7 pages]Instabilities of off-centered vortices in a Bose-Einstein condensateReceived 20 December 2002; revised 7 June 2003; published 25 September 2003 We study numerically the excitations of off-centered vortices in a Bose-Einstein condensate. The displacement of a single vortex and the separation of a doubly quantized vortex are considered. We find that the core-localized excitations of the precessing vortices continue to feature the property which implies that the vortices are unstable. The core-localized, dipolar, and quadrupolar excitations are found to deform continuously as functions of vortex displacements and intervortex separation. © 2003 The American Physical Society URL:
