  • Exact analytical solution of a classical problem of the Josephson tunnel junction 
    Kuplevakhsky, S.V.; Glukhov, A.M. (Физика низких температур, 2010)
    We present the exact and complete analytical solution of the classical problem of the Josephson tunnel junction of arbitrary length W ∈ (0, ∞) in the presence of externally applied magnetic fields and transport currents. ...

    Omelyanchouk, A.N.; Shekhter, R.I. (Физика низких температур, 2010)
    Igor Orestovich Kulik — a prominent physicist and an outstanding representative of Kharkov’s school of theoretical physics, Corresponding member of the National Academy of Sciences of Ukraine and Ukrainian State Prize ...
  • Incoherent microwave-induced resistive states of small Josephson junctions 
    Koval, Y.; Fistul, M.V.; Ustinov, A.V. (Физика низких температур, 2010)
    We report an experimental and theoretical study of low-voltage resistive states that are observed in small tunnel Josephson junctions under microwave radiation. The studied features emerge from Shapiro steps on the ...
  • Josephson currents in point contacts between dirty two-band superconductors 
    Yerin, Y.S.; Omelyanchouk, A.N. (Физика низких температур, 2010)
    We developed microscopic theory of Josephson effect in point contacts between dirty two-band superconductors. The general expression for the Josephson current, which is valid for arbitrary temperatures, is obtained. This ...
  • Macroscopic quantum phenomena in Josephson structures 
    Barone, A.; Lombardi, F.; Rotoli, G.; Tafuri, F. (Физика низких температур, 2010)
    The Josephson effect is a probe of unparalleled performances in the study of a variety of macroscopic quantum phenomena. In the present article an overview of important achievements and challenging trends is given referring, ...
  • Nonadiabatic Josephson dynamics in junctions with in-gap quasiparticles 
    Michelsen, J.; Shumeiko, V.S. (Физика низких температур, 2010)
    Conventional models of Josephson junction dynamics rely on the absence of low-energy quasiparticle states due to a large superconducting gap. With this assumption the quasiparticle degrees of freedom become «frozen out» ...
  • Observation of anisotropic effect of antiferromagnetic ordering on the superconducting gap in ErNi₂B₂C 
    Bobrov, N.L.; Chernobay, V.N.; Naidyuk, Yu.G.; Tyutrina, L.V.; Yanson, I.K.; Naugle, D.G.; Rathnayaka, K.D.D. (Физика низких температур, 2010)
    The point-contact spectra of the Andreev reflection dV / dI curves of the superconducting rare-earth nickel borocarbide ErNi₂B₂C (Tc≈11K) have been analyzed in the «one-gap» and «two-gap» approximations using the generalized ...
  • Persistent currents, flux quantization and magnetomotive forces in normal metals and superconductors (Review Article) 
    Kulik, I.O. (Физика низких температур, 2010)
    The notion of persistent current comes back to orbital currents in normal metals, semiconductors and even insulators displaying diamagnetic behavior in weak magnetic fields, but came to focus at the discovery of current ...
  • Persistent currents in ballistic normal-metal rings 
    Moskalets, M. (Физика низких температур, 2010)
    Recent experiments renewed interest in persistent currents in mesoscopic normal-metal rings. We show that in ballistic rings in high magnetic fields the Zeeman splitting leads to periodic current quenching with period much ...
  • Phase diagram of a current-carrying superconducting film in absence of the magnetic field 
    Bezuglyi, E.V.; Zolochevskii, I.V. (Физика низких температур, 2010)
    It is present the phase diagram for the current states of superconducting films, based on the experimental investigation of the resistive transitions induced by the transport current. It is found that a comparatively narrow ...
  • Quantum behavior of a flux qubit coupled to a resonator 
    Omelyanchouk, A.N.; Shevchenko, S.N.; Greenberg, Ya.S.; Astafiev, O.; Il’ichev, E. (Физика низких температур, 2010)
    The detailed theory for the system of a superconducting qubit coupled to the transmission line resonator is presented. We describe the system by solving analytically and numerically the master equation for the density ...
  • Self-resonant modes in Josephson junctions with a phase discontinuity 
    Nappi, C.; Adamo, M.; Sarnelli, E.; Goldobin, E. (Физика низких температур, 2010)
    We extend the theory of self-resonances in short Josephson junctions to the case of a piecewise constant critical current density and a κ discontinuity of the Josephson phase. We calculate the amplitudes of self-resonances ...
  • Superconducting properties of a two-dimensional doped semiconductor 
    Loktev, V.M.; Turkowski, V. (Физика низких температур, 2010)
    In this paper, we study the superconducting properties of a two-dimensional model with an additional (insulating) gap Δins, which depends on temperature and doping. In particular, we study the doping evolution of the ...
  • Superconductor–insulator transitions of quench-condensed films 
    Goldman, A.M. (Физика низких температур, 2010)
    The superconductor–insulator transitions of quench-condensed ultrathin films of metals are simple examples of continuous quantum phase transitions. Quantum phase transitions differ from thermal phase transitions in that ...

    Kawabata, S.; Asano, Y. (Физика низких температур, 2010)
    We investigate the Josephson transport through ferromagnetic insulators (FIs) by taking into account the band structure of FIs explicitly. Using the recursive Green's function method, we found the formation of a π-junction ...

    Sonne, G.; Peña-Aza, M.E.; Shekhter, R. I.; Gorelik, L.Y.; Jonson, M. (Физика низких температур, 2010)
    We consider a new type of cooling mechanism for a suspended nanowire acting as a weak link between two superconductive electrodes. By applying a bias voltage over the system, we show that the system can be viewed as a ...

    Gurtovoi, V.L.; Ilin, A.I.; Nikulov, A.V.; Tulin, V.A. (Физика низких температур, 2010)
    Experimental results obtained last years corroborate a prediction made by I.O. Kulik forty years ago that the energy dissipation does not result in disappearance of equilibrium circular current observable in the normal ...

    Golubev, D.S.; Semenov, A.G.; Zaikin, A.D. (Физика низких температур, 2010)
