Laser-catalyzed spin-exchange process in a Bose-Einstein condensate
arXiv:1003.1812 · doi:10.1103/PhysRevA.81.031603
Abstract
We show theoretically that it is possible to optically control collective spin-exchange processes in spinor Bose condensates through virtual photoassociation. The interplay between optically induced spin exchange and spin-dependent collisions provides a flexible tool for the control of atomic spin dynamics, including enhanced or inhibited quantum spin oscillations, the optically-induced ferromagnetic-to-antiferromagnetic transition, and coherent matter-wave spin conversion.
