Efimov physics in an ultracold Bose-Fermi gas of $^{40}$K and $^{87}$Rb atoms

ORAL

Abstract

We present measurements of Efimov physics in an ultracold Bose-Fermi gas of $^{40}$K and $^{87}$Rb atoms near an interspecies Feshbach resonance. In particular, we measure loss rates due to inelastic collisions in the trapped gas. We find a resonance in the inelastic collisions of Feshbach molecules with $^{87}$Rb atoms, but no feature in the measured rates of inelastic collisions of three atoms.
