  • 2D Ising-Heisenberg model with quartic interaction 
    Valverde, J.S. (Вопросы атомной науки и техники, 2012)
    We propose a two-dimensional spin-1/2 Ising-Heisenberg model with quartic interaction. In this sense the phase diagram for the model at zero temperature is studied, obtaining four different configurations for the unitary ...

    Basic features of Lagrangian formulation for AdS₄ x CP³ superstring in the framework of OSp(4|6)/(SO(1,3) x U(3)) sigma-model approach are reviewed with the emphasis on realization osp(4|6) background isometry superalgebra ...
  • Advanced Bogolyubov model of imperfect bose gas and superfluidity 
    Bogolyubov, N.N. Jr.; Sankovich, D.P. (Вопросы атомной науки и техники, 2012)
    The equilibrium properties of a system of interacting bosons are studied from a microscopic point of view. We calculate the superfluid density in the Bogolyubov model of imperfect Bose gas. The model superstable Hamiltonian ...
  • Aharonov-Bohm effect: analysis of scattering in the forward direction 
    Vlasii, N.D. (Вопросы атомной науки и техники, 2012)
    The long-standing problem of a divergent behaviour of the Aharonov-Bohm scattering amplitude in the forward direction is reconsidered. We show that this divergence has no physical consequences, being an artefact of the ...
  • Aharonov-Bohm effect in scattering of high-energy particles 
    Sitenko, Yu.A.; Vlasii, N.D. (Вопросы атомной науки и техники, 2012)
    Quantum-mechanical scattering of coherent high-energy charged particles by a magnetic vortex is considered. The vortex core is assumed to be impermeable to scattered particles, and effects of its transverse size are taken ...
  • A method for analysis and optimization of electron accelerator exit devices under bremsstrahlung generation mode 
    Nikiforov, V.I.; Uvarov, V.L. (Вопросы атомной науки и техники, 2012)
    The method of the analysis of a mixed е,X-radiation field along a path of the output target devices of the electron accelerator is proposed. The concept of stopping length of a path and representation of a real path as ...
  • Angular distribution and asymmetries in flavor-changing neutral-current decay B → K* l⁺ l⁻ 
    Korchin, A.Yu.; Kovalchuk, V.A.; Lazarenko, D.O. (Вопросы атомной науки и техники, 2012)
    The fully differential angular distribution for the rare flavor-changing neutral current decay Bd⁰ → K*⁰( → K⁻π⁺)e⁺e⁻ is studied. The emphasis is placed on accurate treatment of the contribution from the processes Bd⁰ → ...
  • A nonlocal extension of the Wentzel field model in the clothed-particle representation 
    Shebeko, A.V.; Frolov, P.A. (Вопросы атомной науки и техники, 2012)
    The clothed particle approach is applied to express the total Hamiltonian of interacting fields in terms of clothed particles. In order to avoid ultraviolet divergences typical of many field theories we introduce some ...

  • Auxiliary ECR heating system for the gas dynamic trap 
    Shalashov, A.G.; Gospodchikov, E.D.; Smolyakova, O.B.; Bagryansky, P.A.; Malygin, V.I.; Thumm, M. (Вопросы атомной науки и техники, 2012)
    Physics aspects of a new system for electron cyclotron resonance heating (ECRH) at the magnetic mirror device Gas Dynamic Trap (GDT, Budker Institute, Novosibirsk) are discussed. This system based on two 400 kW / 54.5 GHz ...
  • A way to incorporation of thermodynamics into quantum theory 
    Golubjeva, O.N.; Sukhanov, A.D. (Вопросы атомной науки и техники, 2012)
    We suggest an approach allowing restrict a gap between macro- and micro descriptions of nature (i.e. between statistical thermodynamics and quantum mechanics) on the basis of a new heat bath model in the form of cold and ...

  • Chaotic motion of dynamic systems with “one” degree of freedom 
    Buts, V.A. (Вопросы атомной науки и техники, 2012)
    It is shown that the regimes with chaotic motion are also inherent in dynamic systems having only one degree of freedom. Such opportunity arises because such systems in the phase space have areas in which the conditions ...
