摘要: We study the stability, form, and interaction of single multiple dark solitons in quasi-one-dimensional dipolar Bose-Einstein condensates. The are found numerically as stationary solutions moving frame a nonlocal Gross Pitaevskii equation characterized function key experimental parameters, namely ratio atomic interactions to van der Waals interactions, polarization angle, condensate width. their integrals motion strongly affected by phonon roton instabilities system. Dipolar matter-wave propagate without dispersion collide elastically away from these instabilities, with contributing an additional repulsion or attraction soliton-soliton interaction. However, close collisions weakly dissipative.
