Slowing down of vortex rings in Bose-Einstein condensates
- 1. School of Mathematics and Statistics, Newcastle University, Newcastle upon Tyne NE1 7RU (United Kingdom)
Description
We consider vortex rings moving in a Bose-Einstein condensate. By numerically solving the Gross-Pitaevskii equation, we show that if the circular shape of the ring is perturbed by helical Kelvin waves of given amplitude and azimuthal wave number, the translational self-induced velocity of the vortex ring is reduced; at large amplitude, the vortex ring halts.
