    Bryk, T.; Mryglod, I. (Condensed Matter Physics, 1999)
    The temperature dependence of the dispersion and damping coefficients of transverse excitations in metallic alloy Mg₇₀Zn₃₀ at the number density n= 0.0435 A⁻³ is studied using the method of generalized collective modes. ...

    Zolotaryuk, A.V.; Christiansen, P.L.; Norde, B.; Savin, A.V. (Condensed Matter Physics, 1999)
    The most simple and straightforward generalization of the standard one-dimensional molecular chain with nearest-neighbour interactions to three dimensions is shown to be a helix backbone with three types of intermolecular ...
  • Multifractal dimension spectra in polymer physics 
    von Ferber, Ch.; Holovatch, Yu. (Condensed Matter Physics, 1999)
    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 absorbing self avoiding walk or random walk.
  • Critical sound in fluids and mixtures 
    Folk, R.; Moser, G. (Condensed Matter Physics, 1999)
    The behaviour of sound is explained within the dynamical renormalization group theory. Non-asymptotic effects are due to the deviation of renormalized couplings from their fixed point values. We calculate the temperature and ...
  • Multicritical behaviour in magnetic fluids 
    Schinagl, F.; Folk, R.; Iro, H. (Condensed Matter Physics, 1999)
    The phases of a magnetic fluid in an external field are considered. As model systems we take an ideal (hard core) gas with Ising interaction and a van der Waals gas with additional Heisenberg interaction. In mean ...
  • Formation of soliton complexes in dispersive systems 
    Bogdan, M.M.; Kosevich, A.M.; Maugin, G.A. (Condensed Matter Physics, 1999)
    The concept of soliton complex in a nonlinear dispersive medium is formulated. It is shown that interacting identical topological solitons in the medium can form bound soliton complexes which move without radiation. This ...
  • Fermi liquid properties of ³He –⁴He mixtures 
    Scho, K.; Krotscheck, E.; Paaso, J.; Saarela, M.; Zillich, R. (Condensed Matter Physics, 1999)
    We calculate microscopically the properties of ³He impurity atoms in ³He-⁴He mixtures, including the spectrum of a single particle and the Fermi–Liquid interaction between ³He atoms. From these, we determine the pressure ...
  • The screening potentials of ion-dipole system adsorbed in ion-dipolar disordered matrices 
    Holovko, M.F.; Polishchuk, Z.V. (Condensed Matter Physics, 1999)
    The replica Ornstein-Zernike equations ion-molecular fluid adsorbed in a disordered ion-molecular matrix were applied. The explicit expressions for the potentials screening by the point particles are obtained. The ...
  • Molecular dynamics study of ternary system K + K⁺q + O⁻²q 
    Shimkevich, A.L.; Shimkevich, I.Yu.; Kuzin, V.V. (Condensed Matter Physics, 1999)
    Results of molecular dynamics (MD) simulation of potassium/oxygen melt, K + K⁺q + O⁻²q , at the temperature of 550 K are presented. MD simulation has been performed for oxygen charge −2q = −1, −2 in the frame of NVT ...
  • On the hydration of ions 
    Heinzinger, K.; Scha, H. (Condensed Matter Physics, 1999)
    This report will concentrate on ions which are produced in nuclear power reactors and/or which are of special interest because of their small radius and/or their high charges, leading to hydrolysis. Mainly the results ...
  • Fermi liquid properties of ³He –⁴He mixtures 
    Schörkhuber, K.; Krotscheck, E.; Paaso, J.; Saarela, M.; Zillich, R. (Condensed Matter Physics, 1999)
    We calculate microscopically the properties of ³He impurity atoms in ³He –⁴He mixtures, including the spectrum of a single particle and the Fermi– Liquid interaction between ³He atoms. From these, we determine the pressure ...
  • Spin-1/2 XX chains in a transverse field with regular nonuniformity or correlated Lorentzian disorder 
    Derzhko, O.; Krokhmalskii, T.; Zaburannyi, O. (Condensed Matter Physics, 1999)
    Using continued fractions we examined the density of states and thermodynamic properties of a few periodic nonuniform spin-1/2 XX chains in a transverse field. We considered the transverse spin dynamics in spin-1/2 XX ...
  • Model description of the H–bonded transuranium complexes 
    Stasyuk, I.V.; Ivankiv, O.L.; Velychko, O.V.; Holubets, T.V. (Condensed Matter Physics, 1999)
    In the framework of configurational model it is established that regions of existence of various forms of actinide hydroxocomplexes at variation of solution pH depend on differences of configuration energies and ...
  • Physical processes in the fuel containing masses interacting with aqueous solutions in the “Shelter” object. Inhomogeneous diffusion of ions UO²⁺₂ , Cs⁺ in the system “glassy nuclear magma – water” 
    Yukhnovskii, I.R.; Tokarchuk, M.V.; Zhelem, R.I. (Condensed Matter Physics, 1999)
    The influence of water on the glassy nuclear magma of the Chornobyl reactor is discussed. To describe it the simplest model for the “glassy nuclear magma–water” system is formulated. Inhomogeneous position- dependent diffusion ...
  • A statistical model for antibody-antigen binding 
    Katletz, S.; Titulaer, U.M. (Condensed Matter Physics, 1999)
    We discuss a statistical model for antibody-antigen binding. The two macromolecules are assumed to be linked by a number of relatively weak bonds (or groups of correlated bonds) that are assumed to open and close ...
  • Master equation approach to protein folding 
    Cieplak, M.; Henkel, M.; Banavar, J.R. (Condensed Matter Physics, 1999)
    The dynamics of two 12-monomer heteropolymers on the square lattice is studied exactly within the master equation approach. The time evolution of the occupancy of the native state is determined. At low temperatures, the ...

    Baryakhtar, I.V. (Condensed Matter Physics, 1999)
    The scheme for describing the kinetic behaviour of solitons in the integrable systems is considered for sine-Gordon and nonlinear Schrödinger equations. The collision integral for solitons is constructed without the ...

    Tkachuk, V.M. (Condensed Matter Physics, 1999)
    We propose a new method for constructing the quasi-exactly solvable (QES) potentials with two known eigenstates using supersymmetric quantum mechanics. General expression for QES potentials with ...
