Bloch Structures in a Rotating Bose-Einstein Condensate
arXiv:cond-mat/0401228 · doi:10.1103/PhysRevLett.93.220402
Abstract
A rotating Bose-Einstein condensate is shown to exhibit a Bloch band structure without the need of periodic potential. Vortices enter the condensate by a mechanism similar to the Bragg reflection, if the frequency of a rotating drive or the strength of interaction is adiabatically changed. A localized state analogous to a gap soliton in a periodic system is predicted near the edge of the Brillouin zone.
