Phase transitions in Bose-Fermi-Hubbard model in the heavy fermion limit: Hard-core boson approach
Phase transitions are investigated in the Bose-Fermi-Hubbard model in the mean field and hard-core boson approximations for the case of infinitely small fermion transfer and repulsive on-site boson-fermion interaction. The behavior of the Bose-Einstein condensate order parameter and grand canonical...
