  • About the new quantum mechanics 
    Sannikov-Proskurjakov, S.S. (Вопросы атомной науки и техники, 2001)
    In our previous papers it is demonstrated that in high energy region (at very small distances) there is a proper quantum theory principally distinguished from the Heisenberg-Schroedinger one (which is well adopted to the ...
  • A new theory of gravity 
    Sannikov-Proskurjakov, S.S. (Вопросы атомной науки и техники, 2001)
    We proceed from the fact that at the quantum level Einsteinian equivalence principle is invalid (it was demonstrated in our previous contribution). In connection with this we have to look for another physical principle for ...
  • Bihamiltonian approach to the gauge models: closed string model 
    Gershun, V.D. (Вопросы атомной науки и техники, 2001)
    The closed string model in the background gravity field and the antisymmetric B-field is considered as the bihamiltonian system in assumption that string model is the integrable model for particular kind of the background ...
  • 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 ...
  • Dicke superradiance on Landau levels 
    Fomin, P.I.; Fomina, A.P. (Вопросы атомной науки и техники, 2001)
    It is shown that in the inverted system of nonrelativistic electrons in rarefied magnetized plasma, when electron density on high Landau levels exceed some critical value defined by its transversal energy, magnetic field ...
  • 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 ...
  • Field strength for graded Yang–Mills theory 
    Ilyenko, K. (Вопросы атомной науки и техники, 2001)
    The graded field strength is defined for osp(2/1;C) non-degenerate gauge algebra. We show that a pair of Grassman odd scalar fields find their place as a constituent part of the graded gauge potential on the equal footing ...
  • Galilean experiment at the elementary particle level 
    Cabbolet, M.J.T.F.; Sannikov-Proskurjakov, S.S. (Вопросы атомной науки и техники, 2001)
    As is well known Einsteinian theory of gravity is based on he so called equivalence principle according of which gravity is identified with accelerated frame and therefore both - acceleration and gravity - are described ...
  • Generation of magnetic and chromomagnetic fields at high temperature in the standard model 
    Demchik, V.I.; Skalozub, V.V. (Вопросы атомной науки и техники, 2001)
    The spontaneous generation of the magnetic and chromomagnetic fields at high temperature is investigated in the Standard Model. The consistent effective potential including the one-loop and the daisy diagrams of all boson ...
  • 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 ...
  • Interactions of elementary particles similar to gravitational one 
    Kulish, Yu.V. (Вопросы атомной науки и техники, 2001)
    It is shown that in the non-relativistic limit the Newtonian gravity law can be derived at the equality of the coupling constants for the electron, proton, neutron interactions with the spin-2 massless particle (quasigraviton). ...
  • 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).

    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 ...
