    Adparticle dynamics at a metallic surface is studied by means of quantum kinetic equations. Kinetic equations of the reaction-diffusion type are written down for nonequilibrium one-particle distribution functions of ...
  • Quantum statistical mechanics of electron gas in magnetic field 
    Dubrovskii, I.M. (Condensed Matter Physics, 2006)
    Electron eigenstates in a magnetic field are considered. Density of the electrical current and an averaged magnetic moment are obtained. Density of states is investigated for two-dimensional electron in a circle that is ...
  • Reduced description of nonequilibrium processes and correlation functions. Divergences and non-analyticity 
    Sokolovsky, A.I. (Condensed Matter Physics, 2006)
    A complete theory for investigation of time correlation functions is developed on the basis of the Bogolyubov reduced description method proceeding from his functional hypothesis. The problem of convergence in the theory ...
  • Sd-model with strong exchange coupling and a metal-insulator phase transition 
    Izyumov, Yu.A.; Chaschin, N.I.; Alexeev, D.S. (Condensed Matter Physics, 2006)
    Sd-exchange model (Kondo lattice model) is formulated for strong sd-coupling within the framework of the Xoperators technique and the generating functional approach. The X-operators are constructed based on the exact ...

    Kremp, D.; Semkat, D.; Bornath, Th. (Condensed Matter Physics, 2006)
    There are many reasons to consider quantum kinetic equations describing the evolution of a many-particle system on ultrashort time scales, e. g. correct energy conservation in nonideal plasmas, buildup of correlations (bound ...
  • Solliton-like order parameter distributions in the critical region
