Theory of strong outcoupling from Bose-Einstein condensates

Abstract

We study the dynamics of a magnetically trapped Bose-Einstein condensate in the presence of an external electromagnetic field coupling trapped, untrapped and antitrapped Zeeman sublevels. For large condensates an approximate analytical solution of the coupled Gross-Pitaevskii equations is given in the regime of strong outcoupling. The theory is developed for the cases of rf-outcoupling within a hyperfine manifold of states, micowave-outcoupling connecting states in two different hyperfine manifolds, and Raman outcoupling.
