Progress toward the magnetoassociation of Lithium and Cesium in an optical tweezer

The field of singly-trapped ultracold molecules has expanded rapidly in the past few years. With the introduction of fast tweezer rearrangement and the demonstrated viability of ground-state preparation by magneto-association coupled with STIRAP, powerful and robust arrays of ultracold molecules for quantum information science are finally being realized after decades of research. Our group reports progress along the conventional path toward the creation of arrays of LiCs molecules trapped in optical tweezers. Both atoms have been successfully trapped and sub-doppler cooled to release-recapture temperatures of less than 100uK. Presented is current work focusing on atomic state preparation in optical tweezers, merging of the two species, and observation of Feshbach resonances of the pairs of atoms. Following work will be on characterizing the Feshbach molecules created in preparation for STIRAP.
