  • Quantum transport equations for Bose systems taking into account nonlinear hydrodynamic processes 
    Hlushak, P.A.; Tokarchuk, M.V. (Condensed Matter Physics, 2014)
    Using the method of nonequilibrium statistical operator by Zubarev, an approach is proposed for the description of kinetics which takes into account the nonlinear hydrodynamic fluctuations for a quantum Bose system. ...
  • 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 ...
  • Quark-parton phase transitions and the entropy problem in quantum mechanics 
    Kim, Y.S. (Вопросы атомной науки и техники, 2001)
    Since Feynman proposed his parton model in 1969, one of the most pressing problems in high-energy physics has been whether partons are quarks. It is shown that the quark model and the parton model are two different ...

    It is established that the growth of quartz in veins in granodiorites of the Andean intrusive complex (the Barchans Islands, West Antarctic) happened in rock crystalbearing veins of steep falling, in which the temperature ...
  • Quasi-active thermal control in LED street lights 
    Trofimov, Yu.V.; Lishik, S.I.; Pershukevich, P.P.; Tsvirko, V.I. (Semiconductor Physics Quantum Electronics & Optoelectronics, 2013)
    In this paper, the hollow heat sink has been studied. The physical and mathematical model of a hollow heat sink and CFD modeling are proposed for fitting the experimental results. It has been shown that the model of a ...
  • Quasiaverages, symmetry breaking and irreducible Green functions method 
    Kuzemsky, A.L. (Condensed Matter Physics, 2010)
    The development and applications of the method of quasiaverages to quantum statistical physics and to quantum solid state theory and, in particular, to quantum theory of magnetism, were considered. It was shown that the ...

    Sumaruk, T.; Sumaruk, P. (Геофизический журнал, 2010)
  • Quasi-Bi-Hamiltonian Structures of the 2-Dimensional Kepler Problem 
    Cariñena, J.F.; Rañada, M.F. (Symmetry, Integrability and Geometry: Methods and Applications, 2016)
    The existence of quasi-bi-Hamiltonian structures for the Kepler problem is studied. We first relate the superintegrability of the system with the existence of two complex functions endowed with very interesting Poisson ...
  • Quasicomplex N=2, d=1 Supersymmetric Sigma Models 
    Ivanov, E.A.; Smilga, A.V. (Symmetry, Integrability and Geometry: Methods and Applications, 2013)
    We derive and discuss a new type of N=2 supersymmetric quantum mechanical sigma models which appear when the superfield action of the (1,2,1) multiplets is modified by adding an imaginary antisymmetric tensor to the target ...
  • Quasi-duo Partial skew polynomial rings 
    Cortes, W.; Ferrero, M.; Gobbi, L. (Algebra and Discrete Mathematics, 2011)
    In this paper we consider rings R with a partial action α of Z on R. We give necessary and sufficient conditions for partial skew polynomial rings and partial skew Laurent polynomial rings to be quasi-duo rings and in this ...
