The application of the associative mean spherical approximation in the theory of nonaqueous electrolyte solutions

Barthel, J.; Krienke, H.; Holovko, M.F.; Kapko, V.I.; Protsykevich, I.A. (Condensed Matter Physics, 2000)

Ionic association in electrolyte solutions is investigated in the framework of chemical models. The associative mean spherical approximation (AMSA) for electrolyte theory is reviewed. It is shown that AMSA in combination with ...
Current states in SNS junction for arbitrary concentrations of nonmagnetic impurities

Svidzinsky, A.V.; Sakhnyuk, V.E. (Condensed Matter Physics, 2000)

The boundary conditions are obtained for NS interface at the presence of arbitrary concentrations of nonmagnetic impurities. The current states in SNS junction are considered. The solution obtained for the current ...
Spin dynamics simulations of collective excitations in magnetic liquids

Omelyan, I.P.; Mryglod, I.M.; Folk, R. (Condensed Matter Physics, 2000)

A novel approach is developed for computer simulation studies of dynamical properties of spin liquids. It is based on the Liouville operator formalism of Hamiltonian dynamics in conjunction with Suzuki-Trotter-like ...
Fractal behaviour of quantum paths in statistical physics

Badiali, J.P. (Condensed Matter Physics, 2000)

The path integral formalism is used to describe the statistical properties of an ideal gas of spinless particles. It is shown that the quantum paths exhibit the same properties in non-relativistic and relativistic domains ...
Mathematical model of a stock market

Gonchar, N.S. (Condensed Matter Physics, 2000)

In this paper we construct a mathematical model of securities market. The results obtained are a good basis for an analysis of any stock market.
Canonical nonequilibrium statistics and applications to Fermi-Bose systems

Ebeling, W. (Condensed Matter Physics, 2000)

The aim of this work is the study of a special class of nonequilibrium systems which admits to ﬁnd exact stationary solutions of the kinetic equations. In particular we investigate canonical-dissipative systems, where ...
Large-scale ﬂuctuations and particle diffusion across external magnetic ﬁeld in turbulent plasmas

Zagorodny, A.; Holod, I. (Condensed Matter Physics, 2000)

Kinetic theory of electromagnetic ﬂuctuations in turbulent plasmas in the external magnetic ﬁeld has been worked out with regard for the effect of ﬂuid-like random motions on ﬂuctuation dynamics. The dielectric ...
On the Widder inversion method in problems of statistical mechanics

Soldatov, A.V.; Seke, J.; Bogolubov, N.N. (Condensed Matter Physics, 2000)

An alternative way of reconstructing a function from its Laplace transform using the Widder inversion method was shown to be useful in treating some problems of nonequilibrium statistical mechanics. As an example of a ...
Phase diagrams of incommensurate ferroelectric NH₄HSeO₄: phenomenological treatment

Kityk, A.V.; Zadorozhna, A.V. (Condensed Matter Physics, 2000)

The phenomenological analysis of the pressure-temperature (P −T ) phase diagram of NH₄HSeO₄ crystals is presented. It is shown that the disagreement between the experimental results and the theory may be removed assuming ...
Oscillatory spectra of surface atoms in strongly anisotropic layered crystal (quasi-1D behaviour)

Vibrations localized near the surface have been analyzed using the Jacobian matrix method taking into account discreteness of the lattice. It has been shown that localized surface vibrations in layered crystals have ...
Scale of radionuclide emission at the Chornobyl Nuclear Power Plant in 1986 (The analysis of estimations)

Checherov, K.P.; Kumshaev, S.B.; Tokarchuk, M.V. (Condensed Matter Physics, 2000)

How much fuel remained inside the Chornobyl Unit 4 after the accident? What is the scale of radionuclide emission in the environment? Till now these questions excite the scientiﬁc community of the world. The critical analysis ...
Critical behaviour of conﬁned systems

Chalyi, A.V.; Chalyi, K.A.; Chernenko, L.M.; Vasilev, A.N. (Condensed Matter Physics, 2000)

The critical phenomena and peculiarities of phase transitions in the conﬁned ﬂuid systems are investigated. A system with the geometry of a planeparallel layer is chosen in order to discuss the inﬂuence of the space ...
Critical transport and critical scattering in ﬂuids
