  • Arimitsu, N.; Arimitsu, T. (Condensed Matter Physics, 2000)
    The optical absorption spectrum in an analytically solvable model of a localized-electron and phonons is investigated using the operator algebra in NonEquilibrium Thermo Field Dynamics (NETFD). The position and the ...
  • Nazarenko, A.; Tretyak, V. (Condensed Matter Physics, 2000)
    Classical relativistic system of point particles coupled with an electromagnetic field is considered in the three-dimensional representation. The gauge freedom connected with the chronometrical invariance of the four-dimensional ...
  • Henning, P.A. (Condensed Matter Physics, 2000)
    In a hot system every excitation acquires a finite lifetime, manifesting itself in a non-zero spectral width. Ordinary damping as well as quantum memory effects arise from this nontrivial spectral function. This report ...

  • Peleschak, R.M. (Condensed Matter Physics, 2000)
    Within the band model we study the electron redistribution around the dislocation wall depending on the conduction band filling ( 0 < n < 1 ) taking into account the electron-deformation coupling. We show that as the conduction ...
  • Yanishevsky, V.S. (Condensed Matter Physics, 2000)
    A variant of a Gaussian approximation in Ising model of phase transition is suggested. The method of functional integration with the application of a variational method is put in the basis of the approach. The Hamiltonian (the ...
  • Burgess, M. (Condensed Matter Physics, 2000)
    Quasiparticle descriptions of nonequilibrium physics hold the promise of tracking the relevant degrees of freedom in calculations of statistical systems, as well as providing an important formal perspective on quantum field ...
  • Sang Pyo, Kim (Condensed Matter Physics, 2000)
    We apply the Liouville-von Neumann (LvN) approach to open systems to describe the nonequilibrium quantum evolution. The Liouville-von Neumann approach is a unified method that can be applied to both time-independent (closed) ...
  • Chattah, A.K.; Caceres, M.O. (Condensed Matter Physics, 2000)
    Using Terwiel’s cumulants the Markovian approximation to arrive to the Quantum Master Equation, for a system interacting with a thermal bath, is revisited. The second order weak coupling approximation is analyzed, then a ...
  • Stasyuk, I.V.; Mysakovych, T.S. (Condensed Matter Physics, 2000)
    Various type contributions to Raman light scattering are investigated for the Hubbard, t − J and pseudospin-electron models. To construct the polarizability operator the microscopic approach is used, which is based on ...
  • Gerasimov, O.I.; Khudyntsev, N.N. (Condensed Matter Physics, 2000)
    The spectrum of the modelled regular superlattice which includes contacts is investigated using the transfer-matrix formalism. It is shown that the separated pair resonances in the chain spectrum (which are distributed ...
  • Rivers, R.J.; Kavoussanaki, E.; Karra, G. (Condensed Matter Physics, 2000)
    Kibble and Zurek have provided a unifying causal picture for the appearance of topological defects like cosmic strings or vortices at the onset of phase transitions in relativistic QFT and condensed matter systems ...
  • Stasyuk, I.V.; Velychko, O.V.; Czapla, Z.; Czukwinski, R. (Condensed Matter Physics, 2000)
    A simple description of thermodynamics of DMAAS and DMAGaS ferroelectric crystals by means of Landau expansion is proposed. Conditions of occurrence of phase transitions are established and their temperatures are obtained. ...
