Abstract
We model the dynamics of condensation in a bimodal trap, consisting of a
large reservoir region, and a tight "dimple" whose depth can be controlled.
Experimental investigations have found that such dimple traps provide an
efficient means of achieving condensation. In our kinetic equations, we include
two- and three-body processes. The two-body processes populate the dimple, and
lead to loss when one of the colliding atoms is ejected from the trap. The
three-body processes produce heating and loss. We explain the principal trends,
give a detailed description of the dynamics, and provide quantitative
predictions for timescales and condensate yields. From these simulations, we
extract optimal parameters for future experiments.
