  • Effect of temporal randomization on the interaction of normalized and anomalous transport 
    Stanislavsky, A.A. (Вопросы атомной науки и техники, 2007)
    The fractional kinetic equations are a natural consequence of non-Gaussian properties in the behavior of many complex systems. We consider the competition between normalized and anomalous transport in the presence of ...
  • Eikonal approximation in the transition radiation theory 
    Shul’ga, N.F.; Syshchenko, V.V. (Вопросы атомной науки и техники, 2007)
    Simple variant of eikonal approximation in transition radiation theory is proposed. Spectral-angular density of radiation on fiber-like targets and nanotubes is calculated using Born and eikonal approximations. The conditions ...
  • Electromagnetic field correlations and sound waves 
    Sokolovsky, A.I.; Stupka, A.A. (Вопросы атомной науки и техники, 2007)
    Statistical operator of the many component plasma has been found on the basis of the Bogolyubov reduced description method and quasi-relativistic quantum electrodynamics. Calculations were carried out in the Hamilton gauge ...
  • Electronic properties of disclinations in carbon nanostructures 
    Sitenko, Yu.A.; Vlasii, N.D. (Вопросы атомной науки и техники, 2007)
    The recent synthesis of strictly twodimensional atomic crystals (monolayers of carbon atoms) is promising a wealth of new phenomena and possible applications in technology and industry. Such materials are characterized by ...
  • Elimination of power divergences in consistent model for spinless and high-spin particle interactions 
    Kulish, Yu.V.; Rybachuk, E.V. (Вопросы атомной науки и техники, 2007)
    The currents for the interaction of the massive high-spin boson (J≥1) with two spinless particles are derived. These currents obey the theorem on currents and fields as well as the theorem on current asymptotics. In one-loop ...
  • Femtosecond scanning, chopping (slicing) and measurement of length of electron bunches by laser pulses: principles of femtosecond oscilloscopes 
    Gazazian, E.D.; Guidi, V.; Ispirian, K.A.; Ispirian, M.K.; Kalantaryan, D.K. (Вопросы атомной науки и техники, 2007)
    The equations of motion of electrons in a plane monochromatic wave with linear, circular and elliptical polarizations are solved taking into account the initial conditions. The cases when the interaction of the electrons ...
  • Finite size induced phenomena in 2D classical spin models 
    Kapikranian, O.; Berche, B.; Holovatch, Yu. (Вопросы атомной науки и техники, 2007)
    We make a short overview of the recent analytic and numerical studies of the classical two-dimensional XY and Heisenberg models at low temperatures. Special attention is being paid to an influence of finite system size L ...
  • From theory to experiment: hadron electromagnetic form factors in space-like and time-like regions 
    Tomasi-Gustafsson, E.; Gakh, G.I.; Rekalo, A.P. (Вопросы атомной науки и техники, 2007)
    Hadron electromagnetic form factors contain information on the intrinsic structure of the hadrons. The pioneering work developed at the Kharkov Physical-Technical Institute in the 60's on the relation between the polarized ...
  • Generalized Kramers’ problem for Lévy particle 
    Sliusarenko, A.Yu.; Chechkin, A.V. (Вопросы атомной науки и техники, 2007)
    We consider a generalization of the classical stochastic problem, namely, how to evaluate the mean escape time and escape probability law of a macroscopic particle, being under the influence of the surrounding medium, from ...
  • Geometrical approach for description of the mixed state in multi-well potentials 
    Berezovoj, V.P.; Bolotin, Yu.L.; Ivashkevych, G.I. (Вопросы атомной науки и техники, 2007)
    We use the so-called geometrical approach [1] in description of transition from regular motion to chaotic one in Hamiltonian systems with potential energy surface that has several local minima. Distinctive feature of such ...
  • Group properties of osp(2/1;C) gauge transformations 
    Ilyenko, K. (Вопросы атомной науки и техники, 2007)
    Given an explicit construction of the grade star hermitian adjoint representation of osp(2/1;C) graded Lie algebra, we consider the Baker-Campbell-Hausdorff formula and find reality conditions for the Grassmann-odd ...
  • Impurity-impurity pair correlation function and paramagnetic-to-ferromagnetic transition in the random Ising model 
    Ivaneyko, D.; Berche, B.; Holovatch, Yu.; Ilnytskyi, Ja. (Вопросы атомной науки и техники, 2007)
    In this Monte Carlo study we concentrated on the influence of non-magnetic impurities arranged as the lines with random orientation on paramagnetic-to-ferromagnetic phase transition in the 3D Ising model. Special emphasize ...
  • Integrable string models and sigma-models of hydrodynamic type in terms of invariant chiral currents 
    Gershun, V.D. (Вопросы атомной науки и техники, 2007)
    We considered two types of string models: on the Riemann space of string coordinates with null torsion and on the Riemann-Cartan space of string coordinates with constant torsion. We used the hydrodynamic approach of ...
  • Intermittency in Hamiltonian systems 
    Slipushenko, S.V.; Tur, A.V.; Yanovsky, V.V. (Вопросы атомной науки и техники, 2007)
    We consider 2D map with the singularity. Here we observe an intermittency behavior. This system can be interpreted in two ways. In the first way this map can arise like a result of quantization of the continuous Hamiltonian ...
  • Kinetic collective excitations in liquids: Heat waves 
    Bryk, T.M.; Mryglod, I.M. (Вопросы атомной науки и техники, 2007)
    We present a theoretical study of non-hydrodynamic propagating processes, which correspond to heat waves in liquids. It is shown, that heat waves can propagate in liquids only on a finite spatial scale and do not appear ...
  • Magnetic monopole and CP symmetry violation at finite temperature 
    Sitenko, Yu.A.; Solovyov, A.V.; Vlasii, N.D. (Вопросы атомной науки и техники, 2007)
    An ideal gas of relativistic massive electrons in the background of a Dirac magnetic monopole is considered. We find that in the case of CP symmetry violation this system acquires, in addition to charge, also squared orbital ...
  • Modeling the precipitation kinetics in systems with strong heterophase fluctuations 
    Turkin, A.A.; Bakai, A.S. (Вопросы атомной науки и техники, 2007)
    The hierarchy of the Becker-Döring rate equations is used to consider the influence of heterophase fluctuations on the kinetics of precipitation in supersaturated solid solutions, including the nucleation stage and the ...
