Collapse of K-Rb Fermi-Bose mixtures in optical lattices

We study a confined mixture of Rb and K atoms in a one dimensional optical lattice, at low temperature, in the quantal degeneracy regime. This mixture exhibits an attractive boson-fermion interaction, and thus above certain values of the number of particles the mixture collapses. We investigate, in...
