Аннотация: We consider the change in the electronic structure of the two-band Hubbard model in the regime of strong electron correlations with spin crossover upon the passage through the crossover point depending on the crystal field growth. An abrupt semimetal-insulator-semimetal transition is detected during the passage through the spin croПоказать полностьюssover point in the absence of the spin-orbit interaction, which is accompanied by a jumpwise redistribution of the partial spectral weight between the poles of the Green function of Fermi quasiparticles. The role of the spin-orbit interaction and the change in the surface topology of surface of one-particle Green function zeros are considered.
