Description:
Author(s): Volodymyr M. Lashkin, Anton S. Desyatnikov, Elena A. Ostrovskaya, and Yuri S. Kivshar We describe, analytically and numerically, topologically nontrivial stationary states with azimuthal modulation of density in a repulsive Bose-Einstein condensate (BEC) confined in a harmonic trap. We show that, depending on the number of density peaks and total topological charge, these states can ... [Phys. Rev. A 85, 013620] Published Tue Jan 17, 2012
