Rotating three-dimensional solitons in Bose-Einstein condensates with gravitylike attractive nonlocal interaction

Maucher, Fabian; Skupin, Stefan; Shen, M.; Krolikowski, Wieslaw


We study formation of rotating three-dimensional high-order solitons (azimuthons) in Bose Einstein condensate with attractive nonlocal nonlinear interaction. In particular, we demonstrate formation of toroidal rotating solitons and investigate their stability. We show that variational methods allow a very good approximation of such solutions and predict accurately the soliton rotation frequency. We also find that these rotating localized structures are very robust and persist even if the...[Show more]
