  • Molecular description of electrolyte solution in a carbon aerogel electrode 
    Kovalenko, A.; Hirata, F. (Condensed Matter Physics, 2003)
    We develop a molecular theory of aqueous electrolyte solution sorbed in a nanoporous carbon aerogel electrode, based on the replica reference interaction site model (replica RISM) for realistic molecular quenched-annea ...
  • Monte Carlo simulation of phase equilibria in Ising fluids and their mixtures 
    Fenz, W.; Folk, R. (Condensed Matter Physics, 2003)
    The mean field theory for the pure Ising fluid was recently extended to binary mixtures of an Ising and a van der Waals fluid. Depending on the relative interaction strengths, their three dimensional phase diagrams show ...
  • Multi-component mixture of dipolar hard spheres with surface adhesion 
    Protsykevich, I.A. (Condensed Matter Physics, 2003)
    Solution of the mean spherical approximation for multi-component model of dipolar hard spheres with surface adhesion is obtained using factorization technique pioneered by Wertheim and Baxter. For the sake of ...
  • Non-linear mechanical, electrical and thermal phenomena in piezoelectric crystals 
    Warkusz, F.; Linek, A. (Condensed Matter Physics, 2003)
    Mechanical, electrical and thermal phenomena occurring in piezoelectric crystals were examined by non-linear approximation. For this purpose, use was made of the thermodynamic function of state, which describes an ...
  • On the existence of a new phase in SASD 
    Lipinski, I.E.; Kuriata, J.; Korynevskii, N.A. (Condensed Matter Physics, 2003)
    Neutron irradiation induced paramagnetic centers are investigated using EPR. It is shown that the observed EPR signal appears to be mainly due to a variety of radicals. Temperature dependence of the EPR linewidth ...
  • Propagating collective excitations in molten salts 
    Bryk, T.; Mryglod, I. (Condensed Matter Physics, 2003)
    Longitudinal as well as transverse dynamics of a molten salt beyond the hydrodynamic region is studied within the generalized collective modes (GCM) approach. An analytical three-variable model is applied to the treatment of ...

    A lattice model of interacting light quantum particles of mass m oscillating in a crystalline field is considered in the framework of an approach based on functional integrals. The main aspects of this approach are ...
  • Quantum stochastic processes: boson and fermion Brownian motion 
    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)

  • 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. ...
