  • Effects of aerogel-like disorder on the critical behavior of O(m)-vector models. Recent simulations and experimental evidence 
    Vasquez, C.; Paredes, R. (Condensed Matter Physics, 2006)
    We review recent results on the effect of a specific type of quenched disorder on well known O(m)-vector models in three dimensions: the XY model (3DXY, m = 2) and the Ising model (3DIS, m = 1). Evidence of changes of ...
  • Electronic structure of large modified nickel nanoclusters 
    Pokhmurskii, V.; Kopylets, V.; Korniy, S. (Condensed Matter Physics, 2006)
    A combined method of quantum-chemical semiempirical approach MNDO and molecular dynamics with atomic potentials was used while studying the growth of large nanoclusters of nickel. Geometry and electronic structure of Ni₄₈₅ ...
  • Energy spectrum of the organic quasi-1D conductors with NNN and correlated hopping 
    Skorenkyy, Yu.; Kramar, O. (Condensed Matter Physics, 2006)
    A model for organic quasi-one-dimensional conductors (TMTTF)₂X and (TMTSF)₂X is considered. The anisotropic character of these compounds is modelled by two different hopping parameters: t between nearest neighbors (NN) ...
  • Entanglement production under electron phonon interaction in a quantum dot 
    Lopez, A.; Medina, E. (Condensed Matter Physics, 2006)
    We consider the quantum dot entangler device introduced by Oliver et al. [1] coupled to a single phonon mode. While we take the phonon interaction to all orders, we perform a fourth order calculation in electron-dot coupling. ...
  • Ergodicity in strongly correlated systems 
    Avella, A.; Mancini, F.; Plekhanov, E. (Condensed Matter Physics, 2006)
    We present a concise and systematic review of the ergodicity issue in strongly correlated systems. After giving a brief historical overview, we analyze the issue within the Green’s function formalism by means of the ...
  • Evolution of the spectrum of the Hubbard model with filling 
    Sherman, A. (Condensed Matter Physics, 2006)
    The diagram technique for the one-band Hubbard model is formulated for the case of moderate to strong Hubbard repulsion. The expansion in powers of the hopping constant is expressed in terms of site cumulants of electron ...
  • Extended quasiparticle approximation for relativistic electrons in plasmas 
    Morozov, V.G.; Ropke, G. (Condensed Matter Physics, 2006)
    Starting with Dyson equations for the path-ordered Green’s function, it is shown that the correlation functions for relativistic electrons (positrons) in a weakly coupled non-equilibrium plasmas can be decomposed into ...
  • Extreme emulsification: formation and structure of nanoemulsions 
    Mason, T.G.; Graves, S.M.; Wilking, J.N.; Lin, M.Y. (Condensed Matter Physics, 2006)
    Nanoemulsions are metastable dispersions of nanodroplets of one liquid that have been ruptured by shear in another immiscible liquid. The ruptured droplets are stabilized against subsequent coalescence by a surfactant. Because ...
  • Ferroelectric-antiferroelectric mixed systems. Equation of state, thermodynamic functions 
    Korynevskii, N.A.; Solovyan, V.B. (Condensed Matter Physics, 2006)
    The problem of equation of state for ferroelectric-antiferroelectric mixed systems in the whole region of a concentration change (06n61) is discussed. The main peculiarity of the presented model turns out to be the possibility ...
  • First-passage time: a conception leading to superstatistics 
    Ryazanov, V.V.; Shpyrko, S.G. (Condensed Matter Physics, 2006)
    To describe the nonequilibrium states of a system we introduce a new thermodynamic parameter – the lifetime (the first passage time) of a system. The statistical distributions that can be obtained out of the mesoscopic ...
  • Functional representation for the grand partition function of a multicomponent system of charged particles: Correlation functions of the reference system 
    Patsahan, O.V.; Mryglod, I.M. (Condensed Matter Physics, 2006)
    Based on the method of collective variables (CV) with a reference system, the exact expression for the functional of the grand partition function of a m-component ionic model with charge and size asymmetry is found. Particular ...
  • Green functions in the renormalized many-body perturbation theory for correlated and disordered electrons 
    Janis, V. (Condensed Matter Physics, 2006)
    The ways of introducing and handling renormalizations in the many-body perturbation theory are reviewed. We stress the indispensable role the technique of Green functions plays in extrapolating the weak-coupling perturbative ...
  • Green’s function formalism for highly correlated systems 
    Mancini, F.; Avella, A. (Condensed Matter Physics, 2006)
    We present the Composite Operator Method (COM) as a modern approach to the study of strongly correlated electronic systems, based on the equation of motion and Green’s function method. COM uses propagators of composite ...
  • Hall effect in organic layered conductors 
    Hasan, R.A.; Kartsovnik, M.V.; Peschansky, V.G. (Condensed Matter Physics, 2006)
    The Hall effect in organic layered conductors with a multisheeted Fermi surfaces was considered. It is shown that the experimental study of Hall effect and magnetoresistance anisotropy at different orientations of ...
  • Historical and interpretative aspects of quantum mechanics: a physicists’ naive approach 
    Berche, B.; Chatelain, C.; Dufour, C.; Gourieux, T.; Karevski, D. (Condensed Matter Physics, 2006)
    Many theoretical predictions derived from quantum mechanics have been confirmed experimentally for the last 80 years. However, interpretative aspects have long been subject to debate. Among them, the question of the ...
  • Homotopy in statistical physics 
    Kenna, R. (Condensed Matter Physics, 2006)
    In condensed matter physics and related areas, topological defects play important roles in phase transitions and critical phenomena. Homotopy theory facilitates the classification of such topological defects. After ...
  • Information model of economy 
    Gonchar, N.S. (Condensed Matter Physics, 2006)
    A new stochastic model of economy is developed that takes into account the choice of consumers are the dependent random fields. Axioms of such a model are formulated. The existence of random fields of consumer’s choice ...
  • Introduction to renormalization 
    Holovatch, Yu. (Condensed Matter Physics, 2006)
    In these lectures I discuss peculiarities of the critical behaviour of “non-ideal” systems as it is explained by the renormalization group approach. Examples considered here include account of the single-ion anisotropy, ...
  • Ionic interaction and conductivity of metallic hydrogen 
    Shvets, V.T.; Savenko, S.V.; Malynovski, Ye.K. (Condensed Matter Physics, 2006)
    We calculate the electroresistivity of metallic hydrogen within the framework of perturbation theory in electronproton interaction. To this end we employ the Kubo linear response theory while using the two-time retarded Green ...
  • Kinetic theory of non-hamiltonian statistical ensembles 
    Zhukov, A.V.; Cao, J. (Condensed Matter Physics, 2006)
    A nonequilibrium statistical operator method is developed for ensembles of particles obeying non-Hamiltonian equations of motion in classical phase space. The main consequences of non-zero compressibility of phase space ...
