Split vortices in optically coupled Bose-Einstein condensates
J. J. Garcia-Ripoll, V. M. Perez-Garcia, F. Sols
We study a rotating two-component Bose-Einstein condensate in which an optically induced Josephson coupling allows for population transfer between the two species. In a regime wher…
Exact solutions of the two-mode model of multicomponent Bose-Einstein condensates
Vadym Vekslerchik, Victor M. Perez-Garcia
We find the explicit solution of a two--mode model used to explain vortex dynamics in multicomponent Bose-Einstein condensates. We prove that all the solutions are constants or per…
Structural instability of vortices in Bose-Einstein condensates
Juan J. Garcia-Ripoll, Gabriel Molina-Terriza, Victor M. Perez-Garcia +1
In this paper we study a gaseous Bose-Einstein condensate (BEC) and show that: (i) A minimum value of the interaction is needed for the existence of stable persistent currents. (ii…
Vortex nucleation and hysteresis phenomena in rotating Bose-Einstein condensates
Juan J. Garcia-Ripoll, Victor M. Perez-Garcia
We study the generation of vortices in rotating Bose--Einstein condensates, a situation which has been realized in a recent experiment (K. W. Madison, F. Chevy, W. Wohlleben, J. Da…
Scattering of light by molecules of light
J. J. Garcia-Ripoll, V. M. Perez-Garcia, W. Krolikowski +1
We study the scattering properties of optical dipole-mode vector solitons recently predicted theoretically and generated in a laboratory. We demonstrate that such a radially asymme…
Nucleation of bended vortices in Bose-Einstein condensates in elongated traps
J. J. Garcia-Ripoll, V. M. Perez-Garcia
We study the generation of vortices in rotating axially elongated magneto-optical traps, a situation which has been realized in a recent experiment (K. W. Madison, F. Chevy, W. Woh…
