This proposal for theoretical and computational work has two components. The goal of the first part is to extend a recent treatment of Bose-Einstein condensates in double-well potentials by Ananikian and the PI to take into account interactions with thermal atoms. The second part of this proposal is intended to assist experimental efforts to produce ultracold molecules from cold atoms. One difficulty is that the spectroscopy of these systems is complex and unknown. Multichannel calculations are required to obtain the important data which is crucially important to the experiments.
