Ultracold and dense samples of ground-state molecules — •Johann Georg Danzl, Manfred Mark, Elmar Haller, Lukas Reichsöllner, and Hanns-Christoph Nägerl — Institut für Experimentalphysik, Universität Innsbruck, Innsbruck, Austria
We produce ultracold and dense samples of rovibrational ground state (RGS) molecules near quantum degeneracy in the presence of an optical lattice. We first associate Cs2 Feshbach dimer molecules out of a lattice-based Mott-insulator state loaded from an atomic Bose-Einstein condensate (BEC) of Cs atoms and then coherently transfer the molecules to the RGS by a four-photon STIRAP process. We discuss improvements to reach higher transfer efficiencies and the next steps towards the production of a BEC of dimer molecules. The work is supported by the Austrian Science Fund FWF in the framework of project P 21555-N20.
