Özet

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.
