Feshbach spectroscopy of potassium-cesium mixtures

I will present our recent results on laser cooling of heteronuclear potassium–cesium mixtures. The talk will outline the key features of our experimental setup and methodology, followed by a discussion of our latest Feshbach spectroscopy measurements, which are promising for the formation of ultracold ground-state molecules. I will show both the confirmation of previously observed resonances in the 39K-Cs mixture and, for the first time, spectroscopic results for the 41K-Cs system.
