The paper is devoted to the theoretical study of elementary permeable objects percolation and its application to real physical objects. Spheres and isotropic oriented capped sticks were chosen as elementary geometrical objects ...

The effect of inactive adsorbed impurities on kinetics of catalytic synthesis of carbon dioxide is investigated in the framework of the lattice-gas model. Namely, two cases of equilibrium impurities with fast, compared with ...

Theoretical study of excitons spectra is offered in this report as for Zn₃P₂ crystals. Spectra are got in the zero approach of the theory of perturbations with consideration of both the anisotropy of the dispersion law and ...

A generalized representation for the scaling form of free energy of the system near the phase transition point is proposed. Explicit expressions for coefficients as functions of the reduced temperature and external field ...

The problem of microscopic description of low-temperature phases in ferro-antiferroelectric mixed compounds is discussed. Those phases (ferro-, antiferroelectric and dipole glass) are interpreted based on the specific ...

Hard wall confined fluid with Yukawa potential of interaction is considered. A solution of the inhomogeneous Ornstein-Zernike equation for the pair correlation function is obtained. The expression for the particle ...

Modified four-sublattice model for Rochelle salt by taking into account piezoelectric interactions with shear strain ε₄, ε₅ and ε₆ is proposed. Components of polarization vector and static dielectric permittivity tensor for ...
