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

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 %...

Description
Summary: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 30 cm, without excessive heating and with an excellent control of its final position. The efficiency is lowered to about 10 % after trapping them in the vertical mixed trap during extended times.
