Optical traps for combining an ultracold Rb gas and single Cs atoms — •Philipp Franzreb, Michael Bauer, Shrabana Chakrabarti, Benjamin Gänger, Farina Kindermann, Jan Phieler, and Artur Widera — Technische Universität Kaiserslautern

Experiments combining single neutral atoms with a many body system require many repetitions of the experimental cycle to obtain significant statistics. Hence it is important to achieve short cycle times with a high production rate of the Bose-Einstein condensate (BEC).

In this poster experimental outline and current status of our optical dipole trap system for a rapid all-optical Rb BEC production and the combination with single Cs atoms is discussed. From a 3D MOT Rb atoms are loaded into a single beam trap, where evaporation is supported due to a crossed beam configuration. Trapping and controlled immersion of single Cs atoms is possible with the aid of an optical lattice formed by an additional anti parallel beam.
