Symmetry-assisted vorticity control in Bose-Einstein condensates
arXiv:nlin/0611052 · doi:10.1103/PhysRevA.75.033618
Abstract
Using group-theoretical methods and numerical simulations we show how to act on the topological charge of individual vortices in Bose-Einstein condensates by using control potentials with appropriate discrete symmetries. As examples of our methodology we study charge inversion and vortex erasing by acting on a set of control laser gaussian beams generating optical dipole traps.
