  • First sound velocity in liquid ⁴He 
    Hryhorchak, O.I. (Condensed Matter Physics, 2015)
    Based on the many-boson system structure factor, which takes into account three- and four-particle direct correlations, there was found the first sound velocity temperature behaviour in liquid ⁴He in the post-RPA approximation. ...

    Patsahan, O. (Condensed Matter Physics, 2015)
    Gas-liquid criticality in the ultrasoft restricted primitive model (URPM) of polyelectrolytes is studied using the collective variables-based theory. For the model, an effective Hamiltonian is derived and explicit expressions ...
  • Gone but not forgotten 
    Henderson, D. (Condensed Matter Physics, 2015)
    In this reminiscence I discuss the influence of Henry Eyring and John Barker upon my life and work. Others, especially my family, have been of even greater personal influence. However, these two great and grand men were ...
  • Heat capacity of liquids: A hydrodynamic approach 
    Bryk, T.; Scopigno, T.; Ruocco, G. (Condensed Matter Physics, 2015)
    We study autocorrelation functions of energy, heat and entropy densities obtained by molecular dynamics simulations of supercritical Ar and compare them with the predictions of the hydrodynamic theory. It is shown that the ...

    On September 1, 2015 a prominent Ukrainian scholar, theoretical physicist, politician and a public figure, full member of the National Academy of Sciences, Doctor of Sciences in mathematics and physics, Professor, and ...
  • In memory of Eduard Vakarin 
    Автор відсутній (Condensed Matter Physics, 2015)
    On May 22, 2015 a sudden regrettable death took away Eduard Vakarin at an early age. Although Vakarin never held a prominent academic position, he established a reputation in the statistical mechanical theory of Condensed ...
  • Meron-cluster simulation of the quantum antiferromagnetic Heisenberg model in a magnetic field in one- and two-dimensions 
    Palma, G.; Riveros, A. (Condensed Matter Physics, 2015)
    Motivated by the numerical simulation of systems which display quantum phase transitions, we present a novel application of the meron-cluster algorithm to simulate the quantum antiferromagnetic Heisenberg model coupled to ...
  • Microphase transitions of block copolymer/homopolymer under shear flow 
    Guo, Y.; Zhang, J.; Wang, B.; Wu, H.; Sun, M.; Pan, J. (Condensed Matter Physics, 2015)
    Cell dynamics simulation is used to investigate the phase behavior of block copolymer/homopolymer mixture subjected to a steady shear flow. Phase transitions occur from transverse to parallel and then to perpendicular ...
  • Modeling the intermixing effects in highly strained asymmetric InGaAs/GaAs quantum well 
    Souaf, M.; Baira, M.; Maaref, H.; Ilahi, B. (Condensed Matter Physics, 2015)
    In this work, we have theoretically investigated the intermixing effect in highly strained In₀.₃Ga₀.₇As/GaAs QW taking into consideration the composition profile change resulting from in-situ indium surface segregation. ...
  • Molecular theory of solvation: Methodology summary and illustrations 
    Kovalenko, A. (Condensed Matter Physics, 2015)
    Integral equation theory of molecular liquids based on statistical mechanics is quite promising as an essential part of multiscale methodology for chemical and biomolecular nanosystems in solution. Beginning with a molecular ...
  • Numerical study of the spin-3/2 Ashkin-Teller model 
    Boudefla, R.; Bekhechi, S.; Hontinfinde, F. (Condensed Matter Physics, 2015)
    The study of the Ashkin-Teller model (ATM) of spin-3/2 on a hypercubic lattice is undertaken via Monte Carlo (MC) simulation. The phase diagrams are displayed and discussed in the physical parameter space. Rich physical ...

    Gorev, V.N.; Sokolovsky, A.I.; Chelbaevsky, Z.Yu. (Condensed Matter Physics, 2015)
    The relaxation of the temperatures and velocities of the components of a quasi-equilibrium two-component homogeneous completely ionized plasma is investigated on the basis of a generalization of the Chapman--Enskog method ...
  • On the composition dependence of thermodynamic, dynamic and dielectric properties of water-methanol model mixtures. Molecular dynamics simulation results 
    Galicia-Andrés, E.; Dominguez, H.; Pusztai, L.; Pizio, O. (Condensed Matter Physics, 2015)
    We have investigated thermodynamic and dynamic properties as well as the dielectric constant of water-methanol model mixtures in the entire range of composition by using constant pressure molecular dynamics simulations at ...
  • On the discontinuity of the specific heat of the Ising model on a scale-free network 
    Krasnytska, M.; Berche, B.; Holovatch, Yu.; Kenna, R. (Condensed Matter Physics, 2015)
    We consider the Ising model on an annealed scale-free network with node-degree distribution characterized by a power-law decay P(K)∼ K-λ. It is well established that the model is characterized by classical mean-field ...
  • Phase transitions in Bose-Fermi-Hubbard model in the heavy fermion limit: Hard-core boson approach 
    Stasyuk, I.V.; Krasnov, V.O. (Condensed Matter Physics, 2015)
