    Kobryn, A.E.; Hayashi, T.; Arimitsu, T. (Condensed Matter Physics, 2003)
    Dynamics of quantum systems which are stochastically perturbed by linear coupling to the reservoir can be studied in terms of quantum stochastic differential equations (for example, quantum stochastic Liouville equation and ...
  • Quasi-one dimensional classical fluids 
    Percus, J.K.; Wang, Q.-H. (Condensed Matter Physics, 2003)
    We study the equilibrium statistical mechanics of simple fluids in narrow pores. A systematic expansion is made about a one-dimensional limit of this system. It starts with a density functional, constructed from ...
  • Replica Ornstein-Zernike equations for positionally frozen Heisenberg systems 
    Lomba, E.; Martin, C. (Condensed Matter Physics, 2003)
    We present the formulation of the Replica Ornstein-Zernike equations for a model of positionally frozen disordered Heisenberg spin system. The results are obtained for various models, one in which the particle ...
  • Role of piezoelectricity in dielectric response of Rochelle salt type crystals 
    Levitskii, R.R.; Zachek, I.R.; Verkholyak, T.M.; Moina, A.P. (Condensed Matter Physics, 2003)
    Comparing the spontaneous polarizations, static and dynamic dielectric properties of piezoelectric Rochelle salt and non-piezoelectric RbHSO₄ we explore the role played by piezoelectric coupling in forming the ...
  • Screening of high-Z grains and related phenomena in colloidal plasmas 
    Bystrenko, O.; Bystrenko, T.; Zagorodny, A. (Condensed Matter Physics, 2003)
    Recent important results are briefly presented concerning the screening of high-Z impurities in colloidal plasmas. The review focuses on the phenomenon of nonlinear screening and its effects on the structure of ...
  • Simulation of synthesis of cluster-assembled nanostructured materials 
    Byshkin, M.S.; Bakai, A.S.; Lazarev, N.P.; Turkin, A.A. (Condensed Matter Physics, 2003)
    A model is described to simulate the formation of nanostructured materials by cluster beam deposition. Clusters are modelled by spherical balls with a given size distribution function, which fall to the substrate and ...
  • Spontaneously appearing discrete moving kinks in nonlinear acoustic chain with realistic potential 
    Metlov, L.S.; Eremeichenkova, Yu.V. (Condensed Matter Physics, 2003)
    Molecular dynamic simulations are performed to investigate a long-time evolution of different initial signals in nonlinear acoustic chains with realistic Exp-6 potential and with power potentials. First, in the chain ...
  • Statistical mechanics in a discrete space-time. Thermodynamics and time-irreversibility 
    Badiali, J.P. (Condensed Matter Physics, 2003)
    The introduction of a discrete space-time represents an attempt to describe the physics at the Planck’s scale. We show that this concept can be also very useful in describing thermodynamics in a pre-relativistic world. ...
  • Strong short-range interactions in one-dimensional proton conductor 
    Stasyuk, I.V.; Vorobyov, O. (Condensed Matter Physics, 2003)
    The behaviour of one-dimensional proton conductor is investigated on the basis of orientational-tunnelling model. The previously proposed technique which permits the proton interactions to be taken into account in the ...
