Vortex Coupler for Atomic Bose-Einstein Condensates

A coherent coupler is proposed to spin a Bose-Einstein condensate composed of ultracold alkali atoms into a vortex state. The proposal is based on a Raman transition induced by two copropagating {sigma}{sup +} and {sigma}{sup {minus}} polarized Laguerre-Gaussian laser beams with different frequencie...
