Ultracold quantum gases with long-range dipolar interactions promise exciting new possibilities for quantum simulation of strongly interacting many-body systems like fractional Mott insulators and supersolid phases. Our experimental apparatus is capable of creating ultracold mixtures of sodium and potassium. Recently we succeeded to produce ultracold 23Na40K molecules in their rotational, vibrational and electronic ground state.
We discuss the experimental apparatus and experimental steps required to achieve this. In particular we investigate the Feshbach molecules creation from the ultracold atomic sample using RF-association near the 89G interspecies Feshbach resonance, efficient ground state transfer to the rovibronic molecular ground state using a stimulated Raman adiabatic passage employing the d3Π(v=5, J=1, Ω=1) intermediate state which mixes with the D1Π electronic state via spin orbit interaction and discuss the properties of the ground state such as it’s lifetime and polarizability.
