  • 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 ...
  • Molecular dynamics simulation of phase transitions in liquid carbon 
    Byshkin, M.S.; Bakai, A.S.; Turkin, A.A. (Вопросы атомной науки и техники, 2007)
    Thermodynamic properties and phase transformations in amorphous carbon and in supercooled liquid carbon are studied by the method of molecular dynamics (MD). The dependence of the diamond melting temperature on pressure ...
  • Multiplet with components of different masses 
    Soroka, D.V.; Soroka, V.A. (Вопросы атомной науки и техники, 2007)
    A principale possibility of the existence of a multiplet including the components with the different masses is indicated. This paper is dedicated to the memory of Anna Yakovlevna Gelyukh (Kalaida).
  • New perturbation theory in QED 
    Filippov, G.M. (Вопросы атомной науки и техники, 2007)
    The new perturbation theory in QED without the ultraviolet catastrophe is constructed.
  • Nonlinear evolution of hypersonic waves with Akhiezer damping and their role in coherent bremsstrahlung in crystals 
    Vodyanitskii, A.A. (Вопросы атомной науки и техники, 2007)
    The asymptotic and numerical analysis of the nonlinear hypersonic wave propagation is fulfilled. Some peculiarities of the linear propagation of a periodic signal, such as the formation of a periodic shock wave, have been ...
  • Nonrelativistic free electron lasers 
    Buts, V.A.; Yegorov, A.M.; Kornilov, E.A.; Marekha, V.I.; Tolstoluzhsky, A.P. (Вопросы атомной науки и техники, 2007)
    The results of the theoretical and experimental investigations of excitation of oscillations by flows of charged particles and its particles dynamics are represented at their motion as in a periodic potential and in a field ...
