  • Article

The temperature behaviour of the energy quantities --- kinetic energy and potential energy components --- is studied in the temperature range below 0.25 eV in the semimetal phase of the extended Hubbard model. It has been established that the collective properties of electronic excitations exhibit various features and depend on temperature. The quantities of energy and order parameters are used for the analysis. The technical difficulties of modeling are mentioned as well as the ways to overcome them.
