Investigation of ferroelectric-antiferroelectric mixed compounds of RADA type
Autor: V. B. Solovyan, N. A. Korynevskii
Publikováno v: Phase Transitions. 80:55-61
The model describing mixed ferroelectric-antiferroelectric compounds of RADA-type is studied in detail. The equations for both ferro- and antiferroelectric order parameters and pair correlation functions of nearest neighbors are solved and analyzed.

Self-consistent approach to magnetic ordering and excited site occupation processes in a two-level system
Autor: V. B. Solovyan, M. A. Korynevskii
Publikováno v: Condensed Matter Physics, Vol 18, Iss 3, p 33706 (2015)
Ferromagnetic ordering in a two-level partially excited system is studied in detail. Magnitudes of magnetization (magnetic order parameter) and lattice ordering (excited level occupation number) are calculated self-consistently. The influence of an e

Improved cubature formulae of high degrees of exactness for the square
Autor: I. P. Omelyan, V. B. Solovyan
Publikováno v: Journal of Computational and Applied Mathematics. 188(2):190-204
The method of constructing minimal cubature rules with high algebraic degrees of exactness is developed by adapting a powerful algorithm for solving the system of nonlinear equations. As a result, new cubature formulae of degrees 15, 17, 19, 21, and

On the Phase Transitions in Ferroelectric-Antiferroelectric Mixed Systems
Autor: V. B. Solovyan, N. A. Korynevskii
Publikováno v: Ferroelectrics. 317:19-24
A new theoretical approach to the investigation of phase transitions in ferroelectric-antiferroelectric mixed systems is proposed. The model Hamiltonian describes both long and short range interactions between particles the total dipole momentum of w
