Cavity-controlled ultracold chemistry — •Tobias Kampschulte¹, 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 propose using the cavity as a non-destructive detector for ultracold molecules, i.e. by avoiding photon scattering. Finally, we present realistic parameters for cavities and how to integrate them into an existing cold-atom setup.
