7/24/2008: Our paper "Accelarating Evaporative Cooling of Atoms into Bose-Einstein condensation in Optical Traps" is published here. In this paper we demonstrate a very simple scheme to achieve the first runaway evaporative cooling in optical traps. The idea is to tilt the dipole trap in a controled fashion to remove hot atoms. Although atoms are removed only in one direction, we proved that the evaporation is effectively 3D and is much more efficient than the conventional trap-weakening method. This scheme can be applied to any atomic species with non-zero magnetic moment (UIUC and NIST have confirmed this point using Rb.) If you cannot access the paper from the above link or have any question about this scheme, please feel free to contact us.
