Abstract

We investigate theoretically the Sisyphus cooling of three-level atoms due to interaction with the evanescent field developed on the surface of a conical-hollow atom trap. We treat the total processes in a fully random way so that quantitative and realistic results are obtained by Monte Carlo simulation. We show that the trapped atoms, when released inside the hollow region, are cooled down to the final temperature of 30 μK, independent of the intial conditions, with negligible loss (about 1%) of the atoms. We also find that the mean height of the collected atoms is about 1 mm from the apex of the conical hollow with the trap radius of 0.5 mm. This system may be useful to realize an atomic funnel or a cold atomic beam for atom optical experiments such as atom interferometer and atom lithography.
