Mean-field analysis of the stability of a K-Rb Fermi-Bose mixture

by M. Modugno, F. Ferlaino, F. Riboli, G. Roati, G. Modugno, M. Inguscio

Abstract:

We compare the experimental stability diagram of a Fermi-Bose mixture of 40K and 87Rb atoms with attractive interaction to the predictions of a mean-field theoretical model. We discuss how this comparison can be used to give a better estimate of the interspecies scattering length, which is currently known from collisional measurements with larger uncertainty.
