Optical focusing of bose-einstein condensates
WebAt least twenty groups have created condensates, and the publication rate on Bose-Einstein condensation has soared following the discovery of the gaseous condensates in 1995 (see Fig. 1). Although atomic condensates and laser light share many properties, they also differ fundamentally: atoms readily interact, photons do not. As a result, the atomic WebWe report on the production of Bose–Einstein condensates of sodium atoms in the hyperfine state F = 2, m F = 2 in a crossed optical dipole trap using D 2 gray molasses. We use the gray molasses sub-Doppler cooling technique …
