Thermodynamic characteristics of the classical n-vector magnetic model in three dimensions
Z. E. Usatenko, M. P. Kozlovskii
The method of calculating the free energy and thermodynamic characteristics of the classical n-vector three-dimensional (3D) magnetic model at the microscopic level without any adj…
Classical Limits of Euclidean Gibbs States for Quantum Lattice Models
Sergio Albeverio, Yuri Kondratiev, Yuri Kozitsky
Models of quantum and classical particles on the d-dimensional cubic lattice with pair interparticle interactions are considered. The classical model is obtained from the correspon…
Laguerre Entire Functions and Related Locally Convex Spaces
Yuri Kozitsky, Lech B. Wolowski
A scale of the Frechet spaces of exponential type entire functions of one complex variable is considered. Certain special properties of subsets of these spaces consisting of Laguer…
Multifractality of Brownian motion near absorbing polymers
Christian von Ferber, Yurij Holovatch
We characterize the multifractal behavior of Brownian motion in the vicinity of an absorbing star polymer. We map the problem to an O(M)-symmetric phi^4-field theory relating highe…
Fokker-Type Confinement Models from Effective Lagrangian in Classical Yang-Mills Theory
A. Duviryak
Abelian potentials of pointlike moving sources are obtained from the nonstandard theory of Yang--Mills field. They are used for the construction of the time-symmetric and time-asym…
The correction-to-scaling exponent in dilute systems
R. Folk, Yu. Holovatch, T. Yavors'kii
The leading correction-to-scaling exponent for the three-dimensional dilute Ising model is calculated in the framework of the field theoretic renormalization group approach. Bo…
Dynamics of transverse correlations in the spin-1/2 isotropic XY chain with a correlated Lorentzian disorder
Oleg Derzhko, Taras Krokhmalskii
Using a numerical approach we examine the dynamics of correlations for the spin- isotropic XY chain with random Lorentzian intersite coupling and transverse field at…
Dynamics and thermodynamics of the pseudospin-electron model in the case of absence of the electron Hubbard correlation. I. The analytical consideration
I. V. Stasyuk, A. M. Shvaika, K. V. Tabunschyk
Dynamics and thermodynamics of the model with local anharmonism in the case of absence of the electron (Hubbard) correlation is investigated in the present work. The correlation fu…
The effect of an external magnetic field on the gas-liquid transition in the Heisenberg spin fluid
T. G. Sokolovska, R. O. Sokolovskii
We present the theoretical phase diagrams of the classical Heisenberg fluid in an external magnetic field. A consistent account of correlations is carried out by the integral equat…
Thermodynamic properties of spin-1/2 transverse XY chain with Dzyaloshinskii-Moriya interaction: Exact solution for correlated Lorentzian disorder
Oleg Derzhko, Johannes Richter
We extend the consideration of the spin-1/2 transverse XY chain with correlated Lorentzian disorder (Phys. Rev. B {\bf 55,} 14298 (1997)) for the case of additional Dzyaloshinskii-…
Multifractal dimension spectra in polymer physics
Christian von Ferber, Yurij Holovatch
We study the multifractal properties of diffusion in the presence of an absorbing polymer and report the numerical values of the multifractal dimension spectra for the case of an a…
On the theory of phase transitions in binary fluid mixtures
O. V. Patsahan
The microscopic approach to the description of the phase behaviour and critical phenomena in binary fluid mixtures is proposed. It is based on the method of collective variables wi…
Magnetic properties of periodic nonuniform spin-1/2 chains in a random Lorentzian transverse field
Oleg Derzhko
Using continued fractions we examine the density of states, transverse magnetization and static transverse linear susceptibility of a few periodic nonuniform spin-1/2 chains i…
Critical exponents of the diluted Ising model between dimensions 2 and 4
Yu. Holovatch, T. Yavors'kii
Within the massive field theoretical renormalization group approach the expressions for the beta- and gamma-functions of the anisotropic mn-vector model are obtained for general sp…

Using numerical approach developed recently we obtained the transverse dynamic structure factor for the spin-1/2 transverse XX chain with correlated Lorentzian disorder.
Pseudospin-Electron Model in Large Dimensions
I. V. Stasyuk, A. M. Shvaika
Energy spectrum and thermodynamics of the pseudospin-electron model introduced at the consideration of the anharmonicity effects in high- superconductors are investigated in t…
Initial static susceptibilities of nonuniform and random Ising chains
Oleg Derzhko, Oles' Zaburannyi, J. W. Tucker
Within the conventional framework of standard linear response theory we have derived exact results for the initial static susceptibilities of nonuniform spin-1/2 Ising chains. The…
Dynamic properties of spin-1/2 XY chains
Oleg Derzhko, Taras Krokhmalskii
We have considered a numerical scheme for the calculation of the equilibrium properties of spin-1/2 XY chains. Within its frames it is necessary to solve in the last resort only th…
Massive Field-Theory Approach to Surface Critical Behavior in Three-Dimensional Systems
H. W. Diehl, M. Shpot
The massive field-theory approach for studying critical behavior in fixed space dimensions is extended to systems with surfaces.This enables one to study surface critical beh…
