Two-dimensional Bose-Einstein condensate in an optical surface trap
D. Rychtarik, B. Engeser, H. -C. Nägerl +1
We report on the creation of a two-dimensional Bose-Einstein condensate of cesium atoms in a gravito-optical surface trap. The condensate is produced a few micrometer above a diele…
Evanescent-wave trapping and evaporative cooling of an atomic gas near two-dimensionality
M. Hammes, D. Rychtarik, B. Engeser +2
A dense gas of cesium atoms at the crossover to two-dimensionality is prepared in a highly anisotropic surface trap that is realized with two evanescent light waves. Temperatures a…
Cold atom gas at very high densities in an optical surface microtrap
M. Hammes, D. Rychtarik, H. -C. Nägerl +1
An optical microtrap is realized on a dielectric surface by crossing a tightly focused laser beam with an horizontal evanescent-wave atom mirror. The nondissipative trap is loaded…
Evaporative cooling of cesium atoms in the gravito-optical surface trap
M. Hammes, D. Rychtarik, R. Grimm
We report on cooling of an atomic cesium gas closely above an evanescent-wave. Our first evaporation experiments show a temperature reduction from 10muK down to 300nK along with a…
Optical and evaporative cooling of cesium atoms in the gravito-optical surface trap
M. Hammes, D. Rychtarik, V. Druzhinina +3
We report on cooling of an atomic cesium gas closely above an evanescent-wave atom mirror. At high densitities, optical cooling based on inelastic reflections is found to be limite…
