Band electron spectrum and thermodynamic properties of the pseudospin-electron model with tunneling splitting of levels
The pseudospin-electron model with tunneling splitting of levels is considered. Generalization of dynamic
 mean-field method for systems with correlated hopping was applied to the investigation of the model. Electron
 spectra, electron concentrations, average values of pseudospins an...

| description | The pseudospin-electron model with tunneling splitting of levels is considered. Generalization of dynamic
mean-field method for systems with correlated hopping was applied to the investigation of the model. Electron
spectra, electron concentrations, average values of pseudospins and grand canonical potential were
calculated within the alloy-analogy approximation. Electron spectrum and dependencies of the electron concentrations
on chemical potential were obtained. It was shown that in the alloy-analogy approximation, the
model possesses the first order phase transition to ferromagnetic state with the change of chemical potential
and the second order phase transition with the change of temperature.
