  • Nonequilibrium action principles for quasi-field 
    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 ...
  • Nonequilibrium quantum evolution of open systems 
    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) ...
  • Quantum dissipation and phenomenological approache 
    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 ...
  • Raman light scattering for systems with strong short-range interaction 
    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 ...
  • Tamm resonances and minibands in the models of atomic chains and superlattices 
    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 ...
  • The onset of phase transitions in condensed matter and relativistic QFT 
    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 ...
  • Thermodynamics and dielectric anomalies of DMAAS and DMAGaS crystals in the region of phase transitions (Landau theory approach) 
    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. ...
