Investigating ultracold chemical processes with NaK molecules — •Jakob Stalmann, Jula Simone Morich, Kai Konrad Voges, and Silke Ospelkaus — Institute of Quantum Optics, Leibniz University Hannover

Ultracold ground-state molecular quantum gases yield highly complex and mostly unknown scattering behavior, ranging from the formation of long-lived collisional complexes to subsequent chemical reactions, photo-excitation or spontaneous spin relaxation.

Here, we present our approach for the detection of such quantum chemical reaction pathways by state-selective product ionization and VMI mass spectroscopy [1] with ultracold ²³Na³⁹K ground-state molecules. The chemically stable, lightweight NaK molecule is ideally suited for such investigations. Alongside deeper studies of ultracold collisions and reaction pathways, this approach will allow us to develop and implement new quantum control techniques for chemical reactions.
