Optimized evaporative cooling using a dimple potential : an efficient route to Bose Einstein condensation.

Ma, Z-Y. and Foot, C. J. and Cornish, S. L. (2004) 'Optimized evaporative cooling using a dimple potential : an efficient route to Bose Einstein condensation.', Journal of physics B : atomic, molecular and optical physics., 37 (15). pp. 3187-3195.

Abstract

The realization of Bose–Einstein condensation of 133Cs relies on an innovative evaporative cooling technique using a dimple potential. Correctly loading an atomic gas into such a potential produces a dense sample with a high phase space density, ideal for evaporative cooling. We have numerically simulated both the loading process and the subsequent evaporative cooling from a dimple potential in order to elucidate the optimization of this technique. Furthermore, we demonstrate that this technique would be effective in cooling 85Rb to quantum degeneracy and describe a simple scheme for its implementation.
