Two-state Bose-Hubbard model in the hard-core boson limit
Phase transition into the phase with Bose-Einstein (BE) condensate in the two-band Bose-Hubbard model with the particle hopping in the excited band only is investigated. Instability connected with such a transition (which appears at excitation energies δ <|t′₍₎|, where |t′₍₎| is the particle hopp...
