Resumen:
We study a confined mixture of Rb and K atoms in a one dimensional opticallattice, at low temperature, in the quantal degeneracy regime. This mixture exhibits an attractive boson-fermion interaction, and thus above certain valuesof the number of particles the mixture collapses.We investigate, in the mean-field approximation, the curve for which thisphenomenon occurs, in the space of number of particles of both species.This is done for different types of optical lattices.
