  • 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 ...
  • Regge Trajectories of Quark Gluon Bags 
    Bugaev, K.A.; Zinovjev, G.M. (Український фізичний журнал, 2010)
    Using an exactly solvable statistical model, we discuss the equation of state of large/heavy and short-living bags of the quark gluon plasma (QGP).We argue that the large width of the QGP bags explains not only the observed ...
  • Resummation in QCD Fractional Analytic Perturbation Theory 
    Bakulev, A.P. (2010)
    We describe the generalization of Analytic Perturbation Theory (APT) for QCD observables, initiated by Radyushkin, Krasnikov, Pivovarov, Shirkov, and Solovtsov, to fractional powers of coupling — Fractional APT (FAPT). The ...
  • Second-Sound Waves in Cryocrystals 
    Khodusov, V.D.; Blinkina, A.A. (Український фізичний журнал, 2010)
    The self-coordinated values of parameters of cryocrystals of orthodeuterium, parahydrogen, and neon (temperature, isotope concentrations, and the sizes of samples), which define the range of second-sound waves existence, ...
  • Self-Consistent Renormalization as an Efficient Realization of Main Ideas of the Bogoliubov−Parasiuk R-operation 
    Kucheryavy, V.I. (Український фізичний журнал, 2010)
    “...At the present time, the intimate connection between causality and the analytic continuation is revealed. So, it is not improbable to develop a subtraction procedure even in the most general case by the use of analytic ...
  • Some Steps on the Way of the Formation of Plasma Turbulence Theory 
    Silin, V.P. (2010)
  • Spin Fluids in Homogeneous and Isotropic Space-times 
    Böhmer, C.G.; Bronowski, P. (Український фізичний журнал, 2010)
    We consider a Weyssenhoff fluid assuming that the space-time is homogeneous and isotropic, therefore being relevant for cosmological considerations of gravity theories with torsion. It is explicitly shown that theWeyssenhoff ...
  • Spontaneous Magnetization of Quantum XY-chain from Finite Chain Form-factors 
    Iorgov, N.Z. (2010)
    Using the explicit factorized formulas for matrix elements (formfactors) of the spin operators between the eigenvectors of the Hamiltonian of a finite quantum XY-chain in a transverse field, the spontaneous magnetization ...
  • Strong Electron Corrections in Short-range Magnetic Order and Electrical Resistance of Homogeneously Disordered Binary Crystals 
    Repetsky, S.P.; Tatarenko, V.A.; Melnyk, I.M.; Len, E.G. (Український фізичний журнал, 2010)
    The formation of both the short-range magnetic order and the electrical conductivity in homogeneously disordered binary crystals under the influence of strong electron correlations is considered (by the example of ...
  • Structural Instability of a Biochemical Process 
    Grytsay, V.I. (Український фізичний журнал, 2010)
    By the example of a mathematical model of a biochemical process, the structural instability of dynamical systems is studied by calculating the full spectrum of Lyapunov indices with the use of the generalized Benettin ...
  • Structure and Dynamics of Granular Materials Perturbed by External Fields 
    Gerasymov, O.I. (Український фізичний журнал, 2010)
    The problem of the description of a local structure of granular materials is discussed within the concept of existence of structural invariants. The superimposition of this approach with the probabilistic arguments concerning ...
  • Study of an Acceptor Impurity Located at the Center of a Sperical Nanoheterostructure 
    Boichuk, V.I.; Bilynskyi, I.V.; Leshko, R.Ya.; Shakleina, I.O. (2010)
    Using the spherical 4x4 Hamiltonian, the discrete states of a hydrogenic acceptor impurity in a spherical GaSb/AlSb nanoheterostructure with various quantum-dot sizes are determined. The energies obtained are compared with ...
  • Temperature Dependence of the Shake-off Effect for Conductivity Electrons in Metals 
    Dzyublik, A.Ya.; Spivak, V.Yu. (2010)
    We analyzed the emission of the conduction electrons in metals caused by any nuclear decay. The refraction of the electron wave at the crystal surface, as well as its attenuation due to scattering by phonons, are taken ...
  • The Analytic Properties of the S-matrix for Arbitrary Interactions Which Externally Pass into the Centrifugal and Rapidly Decreasing Potentials 
    Olkhovsky, V.S. (Український фізичний журнал, 2010)
    The analytic structure of non-relativistic unitary and non-unitary S-matrices is reviewed for the cases of arbitrary interactions (and may be, with the unspecified equations of motion) inside a sphere of radius r ≤ a which ...
