Controlled Generation and Manipulation of Vortex Dipoles in a Bose-Einstein Condensate

Controlled Generation and Manipulation of Vortex Dipoles in a Bose-Einstein Condensate

We propose methods to generate and manipulate vortex dipoles in an atomic Bose-Einstein condensate using Gaussian beams of red- or blue-detuned laser. Vortex dipoles with controlled velocities are shown to be created and launched by a red-detuned beam and by two blue-detuned beams. Critical beam vel...
