Bose-Fermi-Hubbard model in the truncated Hilbert space limit

It is shown that in the Bose-Fermi-Hubbard model which is used for a description of the ultracold atomic boson-fermion mixture in the optical lattice, the n_B ≤ 2 restriction enables one to analyze a more general case of separated lobes Mott insulator in comparison with the case of n_B ≤ 1 (hard-cor...
