Long-range temperature-controlled transport of ultra-cold atoms with an accelerated lattice

Résumé

We report our method for transporting ultracold atoms over macroscopic distances and trapping them back in a vertical mixed trap, consisting of the superposition of a vertical lattice and a transverse confinement beam. The transport is performed with Bloch oscillations allowing us to move up to 25% of a sub-micro-Kelvin atomic cloud on a distance of the order of 30cm, without excessive heating and with a good control of its final position. The efficiency is lowered to about 10% after trapping them back in the vertical mixed trap during extended times.
