Density and Stability in Ultracold Dilute Boson-Fermion Mixtures
arXiv:cond-mat/0703220 · doi:10.1140/epjb/e2007-00288-x
Abstract
We analyze in detail recent experiments on ultracold dilute 87Rb-40K mixtures in Hamburg and in Florence within a mean-field theory. To this end we determine how the stationary bosonic and fermionic density profiles in this mixture depend in the Thomas-Fermi limit on the respective particle numbers. Furthermore, we investigate how the observed stability of the Bose-Fermi mixture with respect to collapse is crucially related to the value of the interspecies s-wave scattering length.
