In the evening of Aug 25th, 2003, our team at the Institute for Experimental Physics at Innsbruck University has created a Bose-Einstein condensate (BEC) of cesium atoms in an optical surface trap. Our experiment is the second to reach condensation of cesium, after its first demonstration on Oct 5th, 2002, in the lab next door. Our trap strongly compresses the atomic cloud in one direction, leading to a two-dimensional condensate!
