Progress towards ultracold RbSr molecules in an optical lattice — •Vincent Barbé, Lukas Reichsöllner, Séverin Charpignon, Klaasjan van Druten, and Florian Schreck — University van Amsterdam, Amsterdam, Netherlands

Our group recently reported on the observation of Feshbach resonances between Rb and Sr atoms in an optical dipole trap [1], and on the experimental investigation of the Rb-Sr electronic ground-state interaction potential [2]. We will present our current efforts aimed at building an optical lattice system that supports a Rb-Sr double-Mott insulator with a high filling fraction, and a high magnetic-field stabilization system for magnetoassociation.
