Simulating Bose-Einstein Condensate
Tom Judd and Mark Fromhold

A simulation of a Bose-Einstein Condensate reflecting from a zone plate structure etched in a silicon surface. The accompanying movie shows the focussing of both reflected and transmitted atoms in a BEC that is incident on a free-standing zone plate.
