  • Analytic and numerical study of a hierarchical spin model 
    Kozitsky, Yu.; Kozlovskii, M.; Krokhmalskii, T. (Condensed Matter Physics, 1999)
    A simple hierarchical scalar spin model is studied analytically and numerically in the vicinity of its critical point. The dependence of the finite size (i.e. calculated for a large but finite number of spins) susceptibility ...
  • Bassalygo-Dobrushin uniqueness for continuous spin systems on irregular graphs 
    Kępa, D.; Kozitsky, Yu. (Condensed Matter Physics, 2008)
    An extension of the Bassalygo-Dobrushin technique of proving uniqueness of Gibbs fields on irregular graphs, developed in [Theory of Probab. Appl. 31, 572–589 (1986)], to the case of continuous spins has been presented.
  • Gibbs states of lattice spin systems with unbounded disorder 
    Kondratiev, Yu.; Kozitsky, Yu.; Pasurek, T. (Condensed Matter Physics, 2010)
  • On thermodynamic states of the Ising model on scale-free graphs 
    Kozitsky, Yu. (Condensed Matter Physics, 2013)
    There is proposed a model of scale-free random graphs which are locally close to the uncorrelated complex random networks with divergent < k²> studied in, e.g., S. N. Dorogovtsev et al, Rev. Mod. Phys., 80, 1275 (2008). ...
  • Quantum anharmonic crystal in functional integral approach 
    Kondratiev, Yu.; Kozitsky, Yu.; Pasurek, T.; Ockner, M.R. (Condensed Matter Physics, 2003)
    A lattice model of interacting light quantum particles of mass m oscillating in a crystalline field is considered in the framework of an approach based on functional integrals. The main aspects of this approach are ...
  • Quantum effects in an anharmonic crystal 
    Kozitsky, Yu. (Condensed Matter Physics, 2002)
    A model of quantum particles performing D -dimensional anharmonic oscillations around their equilibrium positions which form the d -dimensional simple cubic lattice Zd is considered. The model undergoes a structural phase ...
