"Feshbach resonances in a Fermi-Fermi mixture"

Abstract

In this talk I will present our work at the University of Amsterdam on the realization of an ultracold Fermi-Fermi mixture of 6Li and 40K. For its realization we developed a novel 2D-MOT source for cold 6Li. Additionally, I will present a simple theoretical model to accurately calculate all Feshbach resonance positions and widths of a system and our experimental characterization of the broadest Li-K resonance. Finally, I will briefly discuss our present efforts at Harvard University to realize nanoscale traps for single atoms.
