Buffer-gas Cooled Bose-Einstein Condensate

Now well into its second decade, the experimental realization of Bose-Einstein condensation (BEC) in dilute gases has led to revolutionary advances in physics. Since this achievement the field has moved quickly, with innumerable new developments in coherent atom and molecular optics and nonlinear atom optics, the observation of superfluidity in atomic gases, the study of novel quantum systems, and most recently the study of the BEC-BCS crossover. Despite the breadth of new research, however, the basic recipe for BEC is unchanged from its first realization in alkali atoms: pre-cool a hot sample utilizing laser cooling to permit trapping and provide high densities, followed by evaporative cooling to reach quantum degeneracy.

Theoretical Studies of Collisional Processes in Cold and Ultracold Gases

Theoretical Studies of collisional processes and gases at ultracold and cold temperatures in research that is responsive to the experimental program.  Scattering at low temperatures is sensitive to the interaction at large distances of the colliding species.  We calculated the interactions at long-range of a pair of ytterbium atoms (P. Zhang and a. Dalgarno 2008)...
