Cavity-controlled chemical reactions of ultracold atoms — Tobias Kampschulte1, Limei Wang1, •Guangming Liu1, Andreas Köhn2, and Johannes Hecker Denschlag1 — 1Inst. f. Quantenmaterie, Universität Ulm — 2Inst. f. Theoretische Chemie, Universität Stuttgart
Ultracold molecules can be formed from ultracold atoms by photoassociation involving a spontaneous emission process, resulting in a number of final states. Here we want to use strong coupling to an optical cavity to selectively enhance the creation of a certain final state. During this process, a photon will be emitted into the cavity mode which can be detected. A collective enhancement of the effect would enable “superradiant chemistry”. Furthermore, we want to use the cavity for direct optical detection of ultracold molecules.
In the experiment, we are implementing an optical microcavity into an existing Rb BEC apparatus where Rb2 molecules can be produced by magneto- and photoassociation.
The theoretical challenge lies in the precise calculation of molecular potential surfaces and optical transition moments, in particular for trimers and more complex molecules.
