  • Dynamics of explosive instability 
    Buts, V.A.; Koval’chuk, I.K. (Вопросы атомной науки и техники, 2013)
    It was shown that in general case explosive instability dynamics should be described as four wave interaction. The main difference from three wave interaction is that this dynamics may not contain explosive instability. ...
  • Dynamics of ions during development of parametric instability of langmuir waves 
    Belkin, E.V.; Kirichok, A.V.; Kuklin, V.M.; Pryjmak, A.V.; Zagorodny, A.G. (Вопросы атомной науки и техники, 2013)
    Nonlinear regimes of one-dimensional parametric instabilities of long-wave plasma waves are considered for the cases when the average field energy density is less (Zakharov’s model) or greater (Silin’s model) than the ...
  • Kinetics of nonequilibrium electron-phonon system for semiconductors and metals in a strong electric field 
    Karas, V.I.; Potapenko, I.F.; Vlasenko, A.M. (Вопросы атомной науки и техники, 2013)
    Formation of non-stationary nonequilibrium distribution functions (DF) of electrons and phonons is investigated under the action of a strong pulse electric field on metal. For concreteness parameters were taken for nickel ...
  • On the emission spectrum of oscillator trapped in a potential well 
    Kirichok, A.V.; Kuklin, V.M.; Zagorodny, A.G. (Вопросы атомной науки и техники, 2013)
    We study the spectrum of electromagnetic waves emitted by oscillator, trapped in an external potential well. It is assumed that the natural frequency of the oscillator is much greater than the frequency of oscillations in ...
  • On the formation of pulses of coherent radiation in weakly inverted media 
    Kirichok, A.V.; Kuklin, V.M.; Mischin, A.V.; Pryjmak, A.V.; Zagorodny, A.G. (Вопросы атомной науки и техники, 2013)
    A change in the character of maser generation in a two-level system is found when the initial population inversion exceeds some threshold value equal to the square root of the total number of atoms. Above this threshold, ...
  • Paradigms of dynamic chaos 
    Buts, V.A. (Вопросы атомной науки и техники, 2013)
    It is shown that a condition of occurrence of regimes with chaotic behavior of dynamic systems demands more steadfast studying. In particular, it is shown that if we will take into account singular solutions the chaotic ...
  • Particle beams from laser-irradiated solids at ultrahigh intensities 
    Nerush, E.N.; Kostyukov, I.Yu. (Вопросы атомной науки и техники, 2013)
    Laser-solid interactions at the intensity range 10²³…10²⁶ W cm⁻² and the plasma density about 10²⁴ cm⁻³ are studied by means of numerical simulations. This range of parameters is extremely important for various laser ...
  • Pattern formation in unstable viscous convective medium 
    Gushchin, I.V.; Kirichok, А.V.; Kuklin, V.M. (Вопросы атомной науки и техники, 2013)
    The convection in a thin layer of liquid (gas) with poorly heat conducting boundaries and with temperature dependent viscosity are considered. The Proctor-Sivashinsky model is examined in order to study both the pattern ...
  • Relativistically induced transparency and compressed fusion targets 
    Pukhov, A.M.; Kostyukov, I.Yu. (Вопросы атомной науки и техники, 2013)
    We study impact of QED effects on relativistically induced transparency in plasma. The relativictic induced transparency is the key phenomenon in the fast igntion schemes for Inertial Confinement Fusion. We have simulated ...
  • Short-time particle motion in strong standing electromagnetic wave 
    Bashmakov, V.F.; Bashmakov, V.F.; Nerush, E.N.; Kostyukov, I.Yu. (Вопросы атомной науки и техники, 2013)
    The particle motion in the standing electromagnetic wave was investigated on the times much shorter than the wave period. Cases of circular and linear polarizations are considered. The first nonvanishing coefficients in ...
  • Stochastic simulation of the nonlinear kinetic equation with high-frequency electromagnetic fields 
    Andriash, A.V.; Bobylev, A.V.; Brantov, A.V.; Bychenkov, V.Yu.; Karpov, S.A.; Potapenko, I.F. (Вопросы атомной науки и техники, 2013)
    A general approach to Monte Carlo methods for Coulomb collisions is proposed. Its key idea is an approximation of Landau-Fokker-Planck (LFP) equations by Boltzmann equations of quasi-Maxwellian kind. Highfrequency fields ...
  • The influence of the dynamics features of the trapped particles on a spectrum of their oscillations 
    Buts, V.A.; Vavriv, D.M.; Tarasov, D.V. (Вопросы атомной науки и техники, 2013)
    Some features of dynamics of ensembles of coupled linear and nonlinear oscillators are investigated. It is shown that spectral characteristics of this dynamics essentially depend not only on quantity of the oscillators ...
  • Сomputer simulation of the stochastic dynamics in system of two coupled nonlinear oscillators 
    Syaber, S.S.; Anisimov, I.O. (Вопросы атомной науки и техники, 2013)
    Dynamics of two coupled nonlinear oscillators has been studied. Oscillators are represented by conservative LC circuits with nonlinear capacitors. The system exhibits chaotic behavior in some range of initial conditions. ...
