Towards Ultracold Ba⁺-Li - Interactions: The Lithium setup — •F. Thielemann, P. Weckesser, Y. Minet, A. Lambrecht, J. Schmidt, L. Karpa, M. Debatin, and T. Schaetz — Albert-Ludwigs-Universitaet Freiburg

The interplay of ultracold atoms and ions has recently gained interest in the atomic community [1], due to its wide applications in quantum chemistry [2] and quantum control [3]. To control the atom-ion interaction it is necessary to prepare the mixture at ultracold temperatures. Optical trapping of ions [4,5] provides a new pathway to achieve ultracold atom-ion mixtures, as it overcomes the intrinsic micromotion heating effects of a conventional Paul trap [6], currently limiting experiments to collision energies on the order of a few mK.

We present our novel setup aiming to combine Ba⁺ ions and Li atoms in an optical dipole trap. On this poster we focus on the Li branch of the setup. Our design of the oven, the Zeeman slower and the MOT laser system will be introduced in more detail.
