Collisions in a quantum gas of bosonic ²³Na³⁹K molecules — •Mara Meyer zum Alten Borgloh¹, Philipp Gersema¹, Leon Karpa¹, Kai Konrad Voges¹, Jule Caroline Heier¹, Silke Ospelkaus-Schwarzer¹, Charbel Karam², and Olivier Dulieu² — ¹Institut für Quantenoptik, Leibniz Universität Hannover — ²Université Paris-Saclay, CNRS, Laboratoire Aimé Cotton

We report about our experiments with quantum gases of polar ²³Na³⁹K molecules. We discuss both atom-molecule and molecule-molecule collisions including the origin of loss processes in a cloud of chemically stable ²³Na³⁹K molecules.

Furthermore, we discuss a method for suppressing molecular loss using two optical photons at Raman resonance, leading to a potential barrier that protects the colliding molecules from reaching the short range.
