Vortex-vortex interactions in toroidally trapped Bose-Einstein condensates
T. Schulte, L. Santos, A. Sanpera +1
We analyze the vortex dynamics and vortex-vortex interactions in Bose-Einstein condensates confined in toroidal traps. We show that this particular geometry strongly distorts the v…

Generation and evolution of vortex-antivortex pairs in Bose-Einstein condensates
J. -P. Martikainen, K. -A. Suominen, L. Santos +2
We propose a method for generating and controlling a spatially separated vortex--antivortex pair in a Bose-Einstein condensate trapped in a toroidal potential. Our simulations of t…
