  • Bose condensation in (random) traps 
    Jaeck, Th.; Pulé, J.V.; Zagrebnov, V.A. (Condensed Matter Physics, 2009)
    We study a non-interacting (perfect) Bose-gas in random external potentials (traps). It is shown that a generalized Bose-Einstein condensation in the random eigenstates manifests if and only if the same occurs in the ...
  • Bound states of electrons with soliton-like excitations in thermal systems - adiabatic approximations 
    Ebeling, W.; Velarde, M.G.; Chetverikov, A.P. (Condensed Matter Physics, 2009)
    We study the bound states of electrons with solitonic excitations in one and two-dimensional atomic systems. We include Morse interactions between the atoms in a temperature range from low to physiological temperatures. ...
  • Brownian particle in non-equilibrium plasma 
    Lev, B.I.; Tymchyshyn, V.B.; Zagorodny, A.G. (Condensed Matter Physics, 2009)
    The stationary distribution function of Brownian particles in a nonequilibrium dusty plasma is calculated with regard to electron and ion absorption by grains. The distribution is shown to be considerably different from ...
  • Classical and quantum anisotropic Heisenberg antiferromagnets 
    Selke, W.; Bannasch, G.; Holtschneider, M.; McCulloch, I.P.; Peters, D.; Wessel, S. (Condensed Matter Physics, 2009)
    We study classical and quantum Heisenberg antiferromagnets with exchange anisotropy of XXZ-type and crystal field single-ion terms of quadratic and quartic form in a field. The magnets display a variety of phases, including ...
  • Consequences of lattice imperfections and interchain couplings for the critical properties of spin-$1/2$ chain compounds 
    Sirker, J. (Condensed Matter Physics, 2009)
    To allow for a comparison of theoretical predictions for spin chains with experimental data, it is often important to take impurity effects as well as interchain couplings into account. Here we present the field theory ...
  • Dynamical susceptibilities of the Falicov-Kimball model with correlated hopping: general approach 
    Shvaika, A.M.; Farenyuk, O.Ya. (Condensed Matter Physics, 2009)
    The Falicov-Kimball model with correlated hopping is studied in the limit of in nite spatial dimensions. Dynamical susceptibilities are calculated using the generalization of the Dynamical Mean-Field Theory (DMFT), which is ...

  • Effect of adsorbed impurities on catalytic CO oxidation 
    Bzovska, I.S.; Mryglod, I.M. (Condensed Matter Physics, 2009)
    The effect of inactive adsorbed impurities on kinetics of catalytic synthesis of carbon dioxide is investigated in the framework of the lattice-gas model. Namely, two cases of equilibrium impurities with fast, compared with ...
  • Electric properties of the interface quantum dot — matrix 
    Peleshchak, R.M.; Bachynsky, I.Ya. (Condensed Matter Physics, 2009)
    A theoretical research is presented concerning the potential distribution and electric field intensity in the InAs/GaAs nanoheterosystem with InAs QDs within the framework of self-consistent electron-deformation model. ...
  • Enhanced phenomenological models of ion channeling contribution to doping profiles in crystals 
    Bratchenko, M.I.; Dyuldya, S.V.; Bakai, A.S. (Condensed Matter Physics, 2009)
    New phenomenological models are proposed to describe the effect of an ordered lattice structure of crystalline targets on the as-implanted doping profiles of low-energy heavy ions. The models account for the channeling kinetics ...
  • Exact solution of the mixed spin-1/2 and spin-S Ising-Heisenberg diamond chain 
    Čanová, L.; Strečka, J.; Lučivjanský, T. (Condensed Matter Physics, 2009)
    The geometric frustration in a class of the mixed spin-1/2 and spin-S Ising-Heisenberg diamond chains is investigated by combining three exact analytical techniques: Kambe projection method, decoration-iteration transformation ...
  • Excitons into one-axis crystals of zinc phosphide (Zn₃P₂) 
    Stepanchikov, D.M.; Chuiko, G.P. (Condensed Matter Physics, 2009)
    Theoretical study of excitons spectra is offered in this report as for Zn₃P₂ crystals. Spectra are got in the zero approach of the theory of perturbations with consideration of both the anisotropy of the dispersion law and ...
  • Extreme compression behaviour of higher derivative properties of solids based on the generalized Rydberg equation of state 
    Shanker, J.; Singh, B.P.; Jitendra, K. (Condensed Matter Physics, 2009)
    We have derived formulations for the pressure derivatives of bulk modulus up to the third order and for higher order Gr¨uneisen parameters using the generalized free volume theory, and the generalized Rydberg equation of ...
  • Field-controlled spin current in frustrated spin chains 
    Kolezhuk, A.K.; McCulloch, I.P. (Condensed Matter Physics, 2009)
    We study states with spontaneous spin current, emerging in frustrated antiferromagnetic spin-S chains subject to a strong external magnetic field. As a numerical tool, we use a non-Abelian symmetry realization of the density ...
  • Football fever: self-affirmation model for goal distributions 
    Janke, W.; Bittner, E.; Nubaumer, A.; Weigel, M. (Condensed Matter Physics, 2009)
    The outcome of football games, as well as matches of most other popular team sports, depends on a combination of the skills of players and coaches and a number of external factors which, due to their complex nature, are ...
  • Free energy of 3D Ising-like system near the phase transition point 
    Kozlovskii, M.P. (Condensed Matter Physics, 2009)
    A generalized representation for the scaling form of free energy of the system near the phase transition point is proposed. Explicit expressions for coefficients as functions of the reduced temperature and external field ...
  • Gauge field theory approach to spin transport in a 2D electron gas 
    Berche, B.; Bolìvar, N.; López, A.; Medina, E. (Condensed Matter Physics, 2009)
    We discuss the Pauli Hamiltonian including the spin-orbit interaction within an U(1) * SU(2) gauge theory interpretation, where the gauge symmetry appears to be broken. This interpretation offers new insight into the ...

    Clusel, M.; Fortin, J.-Y. (Condensed Matter Physics, 2009)
    We review problems involving the use of Grassmann techniques in the field of classical spin systems in two dimensions. These techniques are useful to perform exact correspondences between classical spin Hamiltonians and ...
