@article{Yukalov2016VortexRA, title={Vortex rings and vortex ring solitons in shaken Bose-Einstein condensate}, author={Vyacheslav I. Yukalov and Alexey N. Novikov and E. P. Yukalova and V. S. Bagnato}, journal={Journal of Physics: Conference Series}, year={2016}, volume={691} }

In a shaken Bose-Einstein condensate, confined in a vibrating trap, there can appear different nonlinear coherent modes. Here we concentrate on two types of such coherent modes, vortex ring solitons and vortex rings. In a cylindrical trap, vortex ring solitons can be characterized as nonlinear Hermite-Laguerre modes, whose description can be done by means of optimized perturbation theory. The energy, required for creating vortex ring solitons, is larger than that needed for forming vortex rings…
