Creation of ultracold Bosonic ³⁹K¹³³Cs Molecules in the rovibrational ground state
Speaker:Charly Beulenkamp (University of Innsbruck)
Abstract:The creation of ultracold heteronuclear molecules by assembly from precooled atoms has led to the realization of molecular gases with electric dipole-dipole interactions in the quantum degenerate regime, with exciting possibilities in the study of many-body dynamics, quantum computation and quantum simulation. One bialkali molecule that has yet to be realized in the ultracold regime is KCs. I will present our recent work on creating on ultracold sample of ³⁹K¹³³Cs molecules in their rovibrational ground state [1,2]. First, I'll discuss the way we produce an ultracold mixture of ³⁹K and ¹³³Cs, two of the more difficult species among the alkalis. We then form up to 7500 weakly bound molecules by means of a magnetic-field ramp over an interspecies Feshbach resonance. We refined the internuclear potentials by fitting to newly observed Feshbach resonances and binding energy measurements, givi
