  • Grain in a Plasma in the Presence of External Electric Field: Kinetic Calculation of Effective Potential and Ionic Drag Force 
    Zagorodny, A.G.; Rogal, I.V.; Momot, A.I.; Schweigert, I.V. (2010)
    Kinetic calculations of the effective grain potential are presented for the case of weakly-ionized plasma in the external electric field. The drag force associated with the ionic drift in the external field is found. It ...
  • Induced Vacuum Polarization of Scalar Field by Impenetrable Magnetic Tube

    Mysakovych, T.S.; Krasnov, V.O.; Stasyuk, I.V. (2010)
    The thermodynamics of a lattice model of intercalation of ions in crystals is considered in the mean-field approximation (MFA). The pseudospin formalism is used for the description of the interaction of electrons with ions, ...
  • Limiting Behavior of the Kinetic Theory for Systems with Multistep Interaction 
    Humenyuk, Y.A.; Tokarchuk, M.V. (2010)
    The kinetic theory of mixtures with a multistep potential (MSP) is considered. A passage to the limit of the smooth continuous potential for the kinetic equation and the potential energy density balance equation is analyzed. ...
  • Low-temperature Ferromagnetism in a Weakly Doped Hubbard Magnet 
    Zubov, E.E. (Український фізичний журнал, 2010)
    In the framework of the diagrammatic method with self-consistent field, the maximum on the temperature dependence of the susceptibility of a weakly doped narrow-band Hubbard magnet below the Curie temperature TC is predicted. ...
  • Magnetization of Dense Neutron Matter in a Strong Magnetic Field 
    Isayev, A.A.; Yang, J. (Український фізичний журнал, 2010)
    Spin polarized states in neutron matter at a strong magnetic field up to ¹⁸ G are considered in the model with the Skyrme effective interaction. Analyzing the self-consistent equations at zero temperature, it is shown that ...
  • Master Equation for State Occupancies of an Open Quantum System 
    Petrov, E.G. (2010)
    Based on the non-equilibrium density matrix method and using the Bogolyubov’s approach for the decoupling of many-particle distribution functions, a closed set of kinetic equations is derived for the state occupancies of ...
  • Modified Bogolyubov’s Derivation of the Two-fluid Hydrodynamics 
    Shygorin, P.; Svidzynskyj, A. (2010)
    A consistent microscopic derivation of the two-fluid hydrodynamics for superfluid helium-4 in the ideal approximation is represented The starting point in our formalism is a system of Heisenberg’s equation of motion for ...
  • Nikolai Nikovaevich Bogolyubov – Great Scientist and Humanist of the XX-th Century 
    Golubjeva, O.N.; Jenkovszky, L.L.; Sukhanov, A.D. (2010)
    August 21, 2009 marked the hundredth anniversary of Nikolai Nikolaevich Bogoliubov,World Science Classic. Bogoliubov’s name entered forever the history of civilization. He was a Scientist of encyclopedic dimensions, one ...
  • Non-commutative Geometry & Physics 
    Wohlgenannt, M. (2010)
    This article is an introduction to the ideas of non-commutative geometry and star products. We will discuss consequences for physics in two different settings: quantum field theories and astrophysics. In case of quantum ...
  • On Chebyshev Polynomials and Torus Knots 
    Gavrilik, A.M.; Pavlyuk, A.M. (2010)
    In this work, we demonstrate that the q-numbers and their two-parameter generalization, the q,p -numbers, can be used to obtain some polynomial invariants for torus knots and links. First, we show that the q-numbers, which ...
  • On Large Volume Moduli Stabilization in IIB Orientifolds 
    Walliser, N.-O. (Український фізичний журнал, 2010)
    I present a brief introduction to the construction of explicit type IIB orientifold compactifications and summarize the ‘Large Volume Scenario’ on compact four-modulus Calabi–Yau manifolds. I discuss the relevance of this ...
  • On the Plasticity of Nonlocal Quantum Correlations 
    Svozil, K. (Український фізичний журнал, 2010)
    The quantum correlations of two or more entangled particles present the possibility of stronger-than-classical outcome coincidences. We investigate binary correlations of quanta with spin one, three-half, and higher in a ...
  • Optimum Concentration of InSb Photodiode for Minimum Low Reverse Bias Leakage Current 
    Moradi, M.; Daraee, M.; Hajian, M.; Forghani, M.A.; Rastgoo, M.; Alipour, A.O. (2010)
    We have investigated a relation between the impurity concentration and the leakage current for three types of InSb diodes. They were fabricated with different impurity concentrations on both sides of the junction such as ...
  • Petrov Noncommutative Topological Quantum Field Theory 
    Moskaliuk, S.S.; Wohlgenannt, M. (Український фізичний журнал, 2010)
    This paper gives a definition of category NC-Einst of noncommutative Einstein spaces, and a Petrov noncommutative topological quantum field theory (NC TQFT) is constructed. We suggest extensions of these ideas which may ...
  • Propagation of Polarized Cosmic Maser Radiation in an Anisotropic Magnetized Plasma 
    Moskaliuk, S.S. (Український фізичний журнал, 2010)
    The polarization plane of the cosmic maser radiation (CMR) can be rotated either in the space-time with a metric of the anisotropic Bianchi-I type or in a magnetized plasma. A unified treatment of these two phenomena is ...
  • Quantum Universe on Extremely Small Space-time Scales 
    Kuzmichev, V.E.; Kuzmichev, V.V. (Український фізичний журнал, 2010)
    The semiclassical approach to the quantum geometrodynamical model is used for the description of the properties of the Universe on extremely small space-time scales. Under this approach, the matter in the Universe has two ...
