  • Account of the longitudinal temperature in cyclotron superradiance 
    Novak, O.P.; Fomina, A.P.; Kholodov, R.I. (Вопросы атомной науки и техники, 2013)
    The phenomenon of cyclotron Dicke superradiance (SR) in the inverted system of nonrelativistic electrons in low density magnetized plasma is considered. It is shown, that account of the longitudinal temperature increases ...
  • Effect of tensor nucleon-nucleon forces on the nucleon-nucleus optical potential 
    Kravchenko, S.M. (Вопросы атомной науки и техники, 2013)
    In the approximation of unpolarized nuclear matter, the optical potential for nucleon-nucleus scattering is calculated on the basis of the effective Skyrme interaction with allowance for tensor nucleon-nucleon forces. It ...
  • Graphene and quantum electrodynamics 
    Gusynin, V.P. (Вопросы атомной науки и техники, 2013)
    A single atomic layer of carbon, graphene, has the low-energy "relativistic- like" gapless quasiparticle excitations which in the continuum approximation are described by quantum electrodynamics in 2+1 dimensions. The ...
  • Gravitational instability of vacuum and the cosmological problem 
    Fomin, P.I. (Вопросы атомной науки и техники, 2013)
    It is shown that, with the account of the gravitational interaction, the physical vacuum can spontaneously partially "dissociate" into particles and antiparticles without violation of any conservation laws. Possible ...
  • Interpretation of positron lifetime spectra via least squares prony method 
    Kul’ment’ev, A.I. (Вопросы атомной науки и техники, 2013)
    A method of numerical analysis of positron annihilation lifetime spectra has been devised. A new approach to determine the number of components in a spectrum was proposed and regularization procedure to solve the inverse ...
  • Microscopical theory, structure of superfluid component and elementary excitation spectrum of the non-relativistic Bose-liquid ⁴He 
    Pashitskij, E.A.; Chumachenko, A.V.; Vilchynskyi, S.I. (Вопросы атомной науки и техники, 2013)
    In frame of selfconsistent microscopical model of the superfluid non-relativistic Bose liquid ⁴He with suppressed due to many-particle effects single-particle condensate and intensive pair coherent condensate the ab initio ...
  • On the theory of radiation at large effective coupling constant 
    Fomin, S.P.; Shul’ga, N.F. (Вопросы атомной науки и техники, 2013)
    A brief historical overview of one of the direction of investigations of high-energy particle interaction with matter at large values of the effective coupling constant is presented. The treatment is based on an example ...
  • Quantum cosmology 
    Shtanov, Yu.V. (Вопросы атомной науки и техники, 2013)
    We discuss quantum-cosmological approach to the problem of initial singularity and origin of our universe, starting with the pioneer idea of quantum creation of the universe put forward by P.I. Fomin.
  • Quantum electrodynamics in the strong pulsed laser fields 
    Roshchupkin, S.P. (Вопросы атомной науки и техники, 2013)
    The some results on the resonant processes of quantum electrodynamics (QED) proceeding in the strong pulsed light fields, realized in modern powerful pulsed lasers is presented. The appearance of resonances in a laser field ...
  • Quantum field methods in the electron cooling 
    Khelemelya, O.V.; Kholodov, R.I. (Вопросы атомной науки и техники, 2013)
    Quantum field methods are proposed to describe the electron cooling process. The influence of the magnetic field and the anisotropy of the temperature distribution of the electron gas are considered in the framework of ...
  • The quantum-field vacuum model of dark energy 
    Fomin, P.I.; Fomina, A.P. (Вопросы атомной науки и техники, 2013)
    The gravitational mechanism of the radical reduction, comparing with the predictions of the local quantum field theory, of physical vacuum energy density is considered. It is shown that the account of self-gravitation of ...
  • The superfluidity of vacuum condensates and the vacuum model of dark matter 
    Fomin, P.I.; Fomina, A.P. (Вопросы атомной науки и техники, 2013)
    We assume that the vacuum condensates, being the bound coherent quantum systems like quantum liquids in macrophysics, have the property of superfluidity. Therefore, they should freely flow into the galactic black holes and ...
  • To the memory of Petr Ivanovich Fomin 
    Storizhko, V.E.; Shul’ga, N.F.; Myroshnichenko, V.I.; Fomin, S.P.; Fomina, A.P.; Gusynin, V.P.; Golod, P.I.; Vil’chinsky, S.I; Shtanov, Yu.V.; Novak, O.P.; Kul’ment’ev, A.I.; Kravchenko, S.M.; Roshchupkin, S.P.; Kholodov, R.I. (Вопросы атомной науки и техники, 2013)
    Petr Ivanovich Fomin, Doctor of Sciences, Professor in theoretical physics, Corresponding Member of the National Academy of Sciences of Ukraine, Head of the Theoretical Physics Department at the Institute of Applied Physics ...
