"Disordered Bose-Einstein Condensates: Probing Quantum and Density Fluctuations in Superfluid-to-insulator transitions"

Presented by Dr. Yong Chen, Purdue University

Friday, May 23, 2008, 2:00 pm — Small Seminar Room, Bldg. 510

Atomic Bose-Einstein condensates (BEC) provide excellent model systems to study quantum matter, with relevance in diverse fields ranging from condensed matter physics to cosmology. I will describe our recent experiments on a BEC subject to a controllable disordered potential, which can drive the BEC from a superfluid to an insulator. The disorder introduces quantum and/or density fluctuations to the BEC and we have studied how these fluctuations evolve during the expansion of the BEC. Ref: Yong P. Chen et al., Phys. Rev.
