Photoassociation Spectroscopy of RbYb near the Yb intercombination lineChristian Sillus1, •Arne Kallweit2, and Axel Görlitz31Heinrich-Heine-Universität Düsseldorf — 2Heinrich-Heine-Universität Düsseldorf — 3Heinrich-Heine-Universität Düsseldorf

Ultracold dipolar molecules constitute a promising system for the investigation of topics like ultracold chemistry, novel interactions in quantum gases, precision measurements and quantum information.

Here we report on experiments in our apparatus for the production of ultracold RbYb molecules. This setup constitutes an improvement of our old apparatus with the new approach of using the intercombination line of Yb for photoassociation. In the new setup a major goal is the efficient production of ground state RbYb molecules.

We employ optical tweezers to transport individually cooled samples of Rb and Yb from their separate production chambers to a dedicated science chamber. Here we start to study interspecies interactions of different isotopes by overlapping crossed optical dipole traps. To explore the pathways towards ground state molecules we start with photoassociation spectroscopy.

Keywords: molecules; photoassociation; RbYb; intercombination; spectroscopy
