Atom-molecule oscillations in a Bose-Fermi mixture.

ORAL

Abstract

We will discuss experiments in which we create a coherent superposition of atom and molecule states in an ultracold gas mixture of $^{87}$Rb and $^{40}$K atoms. Using rapid magnetic-field pulses near an interspecies Feshbach resonance, we couple atoms and heteronuclear molecules. Rabi- and Ramsey-type experiments yield atom-molecule oscillations with relatively large contrast and coherence times up to several hundred microseconds.
