Abstract

We review our experimental progress toward achieving the production of quantum degenerate bosonic polar molecules, ⁴¹K⁸⁷Rb. Our primary goal is to transfer quantum degenerate Feshbach molecules into the absolute ground state via the stimulated Raman adiabatic passage (STIRAP). We have achieved a dual-species Bose–Einstein condensate of ⁴¹K and ⁸⁷Rb in a magnetic trap, which consists of N_K=1.4×10⁴ potassium atoms and N_Rb=3.5×10⁴ rubidium atoms. An optimum optical transition for STIRAP is being identified by a separate experiment based on photoassociation in a dual-species magneto-optical trap of ⁴¹K and ⁸⁷Rb.
