Bright soliton in an expulsive potential in a dipolar condensate
Authors:C Yuce
Institution:Physics Department, Anadolu University, Eskisehir, Turkey
Abstract:We study the stability of matter-wave bright solitons for a dipolar Bose-Einstein condensate in a harmonic potential which is transversely attractive and longitudinally expulsive. We map the regimes of stability as a function of dipole-dipole interaction strength using sech-based variational ansatz. The critical points for collapse and explosion are presented.
Keywords:Soliton  Dipolar Bose-Einstein condensate
