Phase diagrams of the Bose-Hubbard model at finite temperature
The phase transitions in the Bose-Hubbard model are investigated. A single-particle Green's function is calculated
 in the random phase approximation and the formalism of the Hubbard operators is used. The regions of
 existence of the superfluid and Mott insulator phases are est...
