Phase separation of a trapped Bose-Fermi gas mixture: Beyond the Thomas-Fermi approximation - art. no. 043608

Phase separation of a Bose-Fermi gas mixture in a trapping potential is str ongly influenced by the interaction between the fermion and the boson. The stability condition for the mixture at zero temperature is deduced. It is f ound that mixture stability depends on the fermion-boson interaction, the t otal number of the bosons and the fermions, and the trapping frequencies. T he stability conditions for the mixture at finite temperature are also deri ved and discussed.
