Creation of a Molecular Condensate by Dynamically Melting a Mott Insulator
D Jaksch, V Venturi, J I. Cirac, Carl J. Williams, W.H. Zoller
We propose creation of a molecular Bose-Einstein condensate (BEC) by loading an atomic BEC into an optical lattice and driving it into a Mott insulator (MI) phase with exactly two atoms per site. Molecules in a MI state are then created under well defined conditions by photoassociation with essentially unit efficiency. Finally, the MI is melted and a superfluid state of the molecules is created. We investigate the dynamics of this process and study the photoassociation of tightly trapped atoms.
