  • Phase transitions and critical phenomena: universality and non-universal features 
    Ilnytskyi, J.; Holovatch, Y.; Kozitsky, Y. (Condensed Matter Physics, 2013)
    This special issue of the CMP is devoted to phase transitions and critical phenomena. Several recent decades of intensive, sometimes even frantic, and fruitful activities might produce an impression that all principal work ...
  • On thermodynamic states of the Ising model on scale-free graphs 
    Kozitsky, Yu. (Condensed Matter Physics, 2013)
    There is proposed a model of scale-free random graphs which are locally close to the uncorrelated complex random networks with divergent < k²> studied in, e.g., S. N. Dorogovtsev et al, Rev. Mod. Phys., 80, 1275 (2008). ...
  • Self-consistent approach for Bose-condensed atoms in optical lattices 
    Yukalov, V.I. (Condensed Matter Physics, 2013)
    Bose atoms in optical lattices are considered at low temperatures and weak interactions, when Bose-Einstein condensate is formed. A self-consistent approach, based on the use of a representative statistical ensemble, is ...
  • Crossover scaling in the two-dimensional three-state Potts model 
    Nagai, T.; Okamoto, Y.; Janke, W. (Condensed Matter Physics, 2013)
    We apply simulated tempering and magnetizing (STM) Monte Carlo simulations to the two-dimensional three-state Potts model in an external magnetic field in order to investigate the crossover scaling behaviour in the ...
  • On thermodynamic states of the Ising model on scale-free graphs 
    Blackmore, D.; Prykarpatsky, A. (Condensed Matter Physics, 2013)
    A new exactly solvable spatially one-dimensional quantum superradiance model describing a charged fermionic medium interacting with external electromagnetic field is proposed. The infinite hierarchy of quantuum conservation ...
  • A current algebra approach to the equilibrium classical statistical mechanics and its applications 
    Bogolubov, N.; Prykarpatsky, A. (Condensed Matter Physics, 2013)
    The non-relativistic current algebra approach is analyzed subject to its application to studying the distribution functions of many-particle systems at the temperature equilibrium and their stability properties. We show ...
  • Ferroelectric order parameter in the two-particle cluster system near phase transition point: collective variables method 
    Korynevskii, M.A.; Solovyan, V.B. (Condensed Matter Physics, 2013)
    A new approach in the investigation of the order parameter behaviour near ferroelectric phase transition point is suggested. The short range and dipole interactions between particles are taken into account. The logarithmic ...
  • Taras Krokhmalskii’s 60th birthday 
    Автор відсутній (Condensed Matter Physics, 2013)
    Taras Krokhmalskii, a senior research fellow of the Institute for Condensed Matter Physics of the National Academy of Sciences of Ukraine (ICMP), a renowned specialist in the field of condensed matter physics celebrated ...
  • Bertrand Berche's 50th birthday 
    Автор відсутній (Condensed Matter Physics, 2013)
    A story from scientific folklore mentions two principal types of scientists. Scientists of the first type follow a ballistic approach in their research: they go far in a chosen direction, but the area they cover is negligibly ...
  • The Wilson exact renormalization group equation and the anomalous dimension parameter 
    Bervillier, C. (Condensed Matter Physics, 2013)
    The non-linear way the anomalous dimension parameter has been introduced in the historic first version of the exact renormalization group equation is compared to current practice. A simple expression for the exactly marginal ...
  • Mechanism of collisionless sound damping in dilute Bose gas with condensate 
    Slyusarenko, Yu.; Kruchkov, A. (Condensed Matter Physics, 2013)
    We develop a microscopic theory of sound damping due to Landau mechanism in dilute gas with Bose condensate. It is based on the coupled evolution equations of the parameters describing the system. These equations have been ...
  • Energy spectrum and phase diagrams of two-sublattice hard-core boson model 
    Stasyuk, I.V.; Vorobyov, O. (Condensed Matter Physics, 2013)
    The energy spectrum, spectral density and phase diagrams have been obtained for two-sublattice hard-core boson model in frames of random phase approximation approach. Reconstruction of boson spectrum at the change of ...
  • A new critical exponent 'coppa' and its logarithmic counterpart 'hat coppa' 
    Kenna, R.; Berche, B. (Condensed Matter Physics, 2013)
    It is well known that standard hyperscaling breaks down above the upper critical dimension dc, where the critical exponents take on their Landau values. Here we show that this is because, in standard formulations in the ...
  • Phase transitions in the Potts model on complex networks 
    Krasnytska, M.; Berche, B.; Holovatch, Yu. (Condensed Matter Physics, 2013)
    The Potts model is one of the most popular spin models of statistical physics. The prevailing majority of work done so far corresponds to the lattice version of the model. However, many natural or man-made systems are much ...
  • Order parameter of a three-dimensional Ising-like system in the simplest and higher non-Gaussian approximations 
    Pylyuk, I.V. (Condensed Matter Physics, 2013)
    The application of the collective variables method to the study of the behaviour of nonuniversal characteristics of the system in the critical region is illustrated by an example of the order parameter. Explicit expressions ...
  • Universality classes and critical phenomena in confined liquid systems 
    Chalyi, A.V.; Bulavin, L.A.; Chekhun, V.F.; Chalyy, K.A.; Chernenko, L.M.; Vasilev, A.M.; Zaitseva, E.V.; Khrapijchyk, G.V.; Siverin, A.V.; Kovalenko, M.V. (Condensed Matter Physics, 2013)
    It is well known that the similar universal behavior of infinite-size (bulk) systems of different nature requires the same basic conditions: space dimensionality; number components of order parameter; the type (short- or ...
  • Universality versus nonuniversality in asymmetric fluid criticality 
    Anisimov, M.A. (Condensed Matter Physics, 2013)
    Critical phenomena in real fluids demonstrate a combination of universal features caused by the divergence of long-range fluctuations of density and nonuniversal (system-dependent) features associated with specific ...
  • Peculiar points in the phase diagram of the water-alcohol solutions 
    Chechko, V.E.; Gotsulsky, V.Ya.; Malomuzh, M.P. (Condensed Matter Physics, 2013)
    The work is devoted to the investigation of nontrivial behavior of dilute water-alcohol solutions. The temperature and concentration dependencies of the contraction for aqueous solutions of ethanol and methanol are analyzed. ...
  • Liquid gas phase transition at and below the critical point 
    Yukhnovskii, I.R.; Kolomiets, V.O.; Idzyk, I.M. (Condensed Matter Physics, 2013)
    This article is a continuation of previous works (see Yukhnovskii I.R. et al., J. Stat. Phys, 1995, 80, 405 and references therein), where we have described the behavior of a simple system of interacting particles in the ...
