Atom-molecule and molecule-molecule collisions in ultracold quantum gas mixtures of 39K atoms and rovibronic 23Na39K ground-state molecules — •Philipp Gersema1, Mara Meyer zum Alten Borgloh1, Kai Konrad Voges1, Torsten Hartmann1, Leon Karpa1, Alessandro Zenesini2, and Silke Ospelkaus1 — 1Leibniz Universität Hannover, Institut für Quantenoptik — 2Universita di Trento, Dipartimento di Fisica
Ultracold heteronuclear molecules enable the study of fascinating new physical phenomena in the quantum realm. These arise from the degrees of freedom of vibration and rotation and the large permanent dipole moment of heteronuclear molecules. However, especially for the investigation of novel phenomena in quantum many-body physics, a precise understanding of the collision properties of heteronuclear polar molecules is mandatory. Here we report on our experiments on collisions in pure quantum gases of bosonic NaK molecules and atom-molecule mixtures. We discuss photoinduced collisional processes and hyperfine dependent atom-molecule scattering and report on our progress towards photoassociation of weakly bound triatomic NaK2 molecules.
