The effect of the high pressure on the electronic properties of NiO is studied within the multielectron approach. The low energy physics is described by the effective Hubbard model based on Ni d-electrons and O p-electrons in three charge sectors of

The effect of high pressure on the electronic characteristics of CoO is analyzed in the framework of the multielectron model of transition metal oxides. The specific features of spin crossover for d7 terms of Co2+ are compared to those characteristic

The ground and excited states of the pheromone molecules produced by xylophagous insects (the bark beetle Ips typographus L., the black fir sawyer beetle Monochamus urussovi Fisch., and the black pine sawyer M. galloprovincialis Oliv.) were modeled u

The phase diagram of an antiferromagnet with the spin crossover from the high-spin to low-spin state with S = 0 with increasing external pressure has been calculated with regard to the pressure dependence of the exchange integral. The calculated resu

To study non-Heisenberg effects in the vicinity of spin crossover in strongly correlated electron systems we derive an effective low-energy Hamiltonian for the two-band Kanamori model. It contains Heisenberg high-spin term proportional to exchange co

The correlation between the kinetic stability of molecules against temperature and variations in their geometric structure under optical excitation is investigated by the example of different organic pheromone molecules sensitive to temperature or ul

For Mott insulators with tetrahedral environment, the effective Hubbard parameter Ueff is obtained as a function of pressure. This function is not universal. For crystals with d5 configuration, the spin crossover suppresses electron correlations, whi

A model of ecological second-order transitions has been proposed as a description of altitude-belt zonality of wood vegetation. The objects of the study are forest cenoses on the northern slope of Kulumyss Ridge (the Sayan Mauntains), while the resul

For a description of the successional processes in forest coenoses and the spatial distribution of tree species, an approach using phase transitions models is proposed. We introduced a variable equation and phase transition models that describe proce
