  • Critical behaviour of a 3D Ising-like system in the ρ⁶ model approximation: Role of the correction for the potential averaging 
    Pylyuk, I.V.; Ulyak, M.V. (Condensed Matter Physics, 2012)
    The critical behaviour of systems belonging to the three-dimensional Ising universality class is studied theoretically using the collective variables (CV) method. The partition function of a one-component spin system is ...
  • Critical behaviour of confined systems

    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 currents and relaxation in Josephson media 
    D’yachenko, A.I.; Stankowski, J. (Физика низких температур, 1996)
    The main aim of this paper is to show that Josephson critical current lc stability to high magnetic fields H » Hс₁ tends to hysteretic relaxation rate of the Josephson media critical current Jc(t) and produces a change in ...
  • Critical energy in the cyclotron heating of ions in an ECR plasma source 
    Gutiérrez-Tapia, C.; Hernández-Aguirre, O. (Вопросы атомной науки и техники, 2002)
    The problem of plasma cyclotron heating in ECR plasma sources, to sustain the discharge, remains important at present. There are two methods for the analysis of this problem. The first one is the one particle stochastic ...
  • Critical indices of the ferroelectric phase transition in TGS crystals 
    Myshchyshyn, O.; Andriyevsky, B.; Romanyuk, M. (Condensed Matter Physics, 1999)
    Temperature dependencies of retardation, electron susceptibility and linear thermal expansion for three crystal-physic directions are obtained by means of optical investigations of the ferroelectric phase transition in ...
  • Criticality of the random-site Ising model: Metropolis, Swendsen-Wang and Wolff Monte Carlo algorithms 
    Ivaneyko, D.; Ilnytskyi, J.; Berche, B.; Holovatch, Yu. (Condensed Matter Physics, 2005)
    We apply numerical simulations to study of the criticality of the 3D Ising model with random site quenched dilution. The emphasis is given to the issues not being discussed in detail before. In particular, we attempt a ...
  • Critical line of the Φ⁴ scalar field theory on a 4D cubic lattice in the local potential approximation 
    Caillol, J.-M. (Condensed Matter Physics, 2013)
    We establish the critical line of the one-component Φ⁴ (or Landau-Ginzburg) model on a simple four dimensional cubic lattice. Our study is performed in the framework of the non-perturbative renormalization group in the ...
  • Critical parameter calculation of a binary melt crystallization in stationary regime 
    Kanishchev, V.N.; Barannik, S.V. (Functional Materials, 2004)
    Taking into account the latent melting heat and the heat conductivity differences between the solid and liquid phases, the stationary heat and mass transfer problem in a bounded domain region of a crystal/melt system has ...
  • Critical parameters and pair correlations in confined multicomponent liquids 
    Vasilev, A.N.; Chalyi, A.V. (Condensed Matter Physics, 2006)
    We investigate multicomponent finite-size liquid systems with geometry of plane-parallel layer and cylinder. We consider these systems are being affected by weak external field which causes their anisotropy. For these systems ...
  • Critical phenomena and critical dimensions in anisotropic nonlinear systems 
    Babich, A.V.; Berezovsky, S.V.; Kitcenko, L.N.; Klepikov, V.F. (Вопросы атомной науки и техники, 2012)
    The model that allows one to generalize the notions of the multicritical and Lifshitz points is considered. The model under consideration includes the higher powers and derivatives of order parameters. Critical phenomena ...
  • Critical phenomena for systems under constraint 
    Izmailian, N.; Kenna, R. (Condensed Matter Physics, 2014)
    It is well known that the imposition of a constraint can transform the properties of critical systems. Early work on this phemomenon by Essam and Garelick, Fisher, and others, focused on the effects of constraints on the ...
  • Critical phenomena in anisotropic multidimensional systems 
    Babich, A.V.; Klepikov, V.F. (Problems of Atomic Science and Technology, 2022)
    A class of models, which describe the critical phenomena in anisotropic multidimensional systems with both higher-order spatial order parameter (OP) derivatives and higher OP nonlinearities is proposed. Such models may be ...
  • Critical point calculation for binary mixtures of symmetric non-additive hard disks 
    Gózdz, W.T.; Ciach, A. (Condensed Matter Physics, 2016)
    We have calculated the values of critical packing fractions for the mixtures of symmetric non-additive hard disks. An interesting feature of the model is the fact that the internal energy is zero and the phase transitions ...

    Heidarkhani, S.; Ge, B. (Український математичний журнал, 2014)
    We establish the existence of at least three solutions for elliptic problems driven by a p(x)-Laplacian. The existence of at least one nontrivial solution is also proved. The approaches are based on the variational methods ...
