  • Branes in string theory 
    Sorokin, D.P. (Вопросы атомной науки и техники, 2007)
    We give a simple overview of some basic aspects of the dynamics of branes in string theory and of their role in the attempts to get from String Theory a realistic model of fundamental interactions of elementary particles.
  • Clothed particle representation in quantum field theory: boost generators of the Poincaré group 
    Korda, V.Yu.; Frolov, P.A. (Вопросы атомной науки и техники, 2007)
    The method of the unitary clothing transformations is used to construct the generators of the Poincaré group in the instant form of relativistic dynamics in the second and third orders in the coupling constant. It is shown ...
  • Clothed particle representation in quantum field theory: mass renormalization 
    Korda, V.Yu.; Shebeko, A.V. (Вопросы атомной науки и техники, 2007)
    The method of unitary clothing transformations is applied in the model involving nucleon and neutral pion fields interacting via the regularized pseudoscalar Yukawa-type coupling. In this approach the mass counterterms are ...
  • Correlation functions in BCS-BEC transition region of nuclear matter 
    Isayev, A.A. (Вопросы атомной науки и техники, 2007)
    The density, spin and isospin correlation functions in nuclear matter with a neutron-proton (np) condensate are calculated to study the possible signatures of the BEC-BCS crossover in the low-density region. It is shown ...
  • 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 ...
  • 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 ...
  • 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 ...
  • 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 ...
  • 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).
  • On six-dimentional Dirac equation and some relations between polarisations of the spin ½ particle 
    Lyubchenko, M.V.; Stepanovsky, Yu.P. (Вопросы атомной науки и техники, 2007)
    Through the six-dimensional description of polarized spin ½ particles we obtain some formulae representing general properties of polarization phenomena. The obtained relations between polarizations are used for consideration ...
  • On some properties of 2-D Weyl equation for charged massless spin ½ particle 
    Ovcharenko, I.E.; Stepanovsky, Yu.P. (Вопросы атомной науки и техники, 2007)
    We discuss some properties of Dirac equation and 2-D Weyl equation for a charged massless spin ½ particle in a stationary inhomogeneous magnetic field such as Bloch theorem and Aharonov-Casher theorem and its relation to ...
  • Tensionless super p-branes in extended superspaces 
    Uvarov, D.V.; Zheltukhin, A.A. (Вопросы атомной науки и техники, 2007)
    Analyzed is the symmetry structure of tensionless super p-branes in N=1 superspace enlarged by commuting antisymmetric tensor coordinates zm1 - mp associated to tensorial central charge generators of N=1 extended superalgebra. ...
  • The method of unitary clothing transformations in quantum field theory: the bound-state problem and the S-matrix 
    Shebeko, A.V. (Вопросы атомной науки и техники, 2007)
    Being aimed at reformulating quantum field theory (QFT) within the notion of the so-called clothed particles and interactions between them we consider the problem of finding the simplest eigenstates of the total field ...
  • The twistor string: a new framework to study Yang-Mills theories, and its spacetime formulation 
    Bandos, I.A.; de Azcárraga, J.A.; Miquel-España, C. (Вопросы атомной науки и техники, 2007)
    We give a brief review of the twistor string approach to supersymmetric Yang-Mills theories with an emphasis on the different formulations of (super)string models in supertwistor space and their superspace form. We discuss ...
  • The θ-twistor versus the supertwistor 
    Zheltukhin, A.A. (Вопросы атомной науки и техники, 2007)
    We introduce the θ-twistor, which is a new supersymmtric generalization of the Penrose twistor and is also alternative to the supertwistor. The θ-twistor is a triple of spinors including the spinor θ extending the Penrose’s ...
  • Vertex clothing in quantum field theory 
    Korda, V.Yu.; Yeletskikh, I.V. (Вопросы атомной науки и техники, 2007)
    The problem of the vertex renormalization in quantum field theory is tackled via the implementation of the unitary clothing transformation method. In the model of charged spinless nucleon and scalar meson fields coupled ...
