Pressure-temperature phase diagram of the generalized Hubbard model with correlated hopping at half-filling
In the present paper, the pressure-temperature phase diagram of a generalized Hubbard model with correlated hopping in a paramagnetic state at half-filling is determined by means of a generalized mean-field approximation in the Green function technique. The constructed phase diagram describes th...

| description |
In the present paper, the pressure-temperature phase diagram of a generalized
Hubbard model with correlated hopping in a paramagnetic state
at half-filling is determined by means of a generalized mean-field approximation
in the Green function technique. The constructed phase diagram
describes the metal-to-insulator transition with increasing temperature, and
the insulator-to-metal transition under the action of external pressure. The
phase diagram can explain the paramagnetic region of the phase diagrams
of some transition metal compounds |
