  • 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 ...
  • Zagoskin, A.M. (Физика низких температур, 2010)
    The progress in experimental techniques and theoretical modeling made possible to fabricate and test macroscopic structures, which use quantum coherent solid state qubits as building blocks. The results of such quantum ...
  • 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 ...
  • 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 ...
  • 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» ...
  • Golubev, D.S.; Semenov, A.G.; Zaikin, A.D. (Физика низких температур, 2010)
    Combining scattering matrix theory with non-linear σ-model and Keldysh technique we develop a unified theoretical approach enabling one to non-perturbatively study the effect of electron–electron interactions on weak ...
  • 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 ...
  • Parafilo, A.V.; Krive, I.V.; Bogachek, E.N.; Landman, U.; Shekhter, R.I.; Jonson, M. (Физика низких температур, 2010)
    The novel phenomenon of chiral tunneling in metallic single-wall carbon nanotubes is considered. It is induced by the interplay of electrostatic and pseudomagnetic effects in electron scattering in chiral nanotubes and is ...
  • 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 ...
  • 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 ...
  • 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 ...
  • 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 ...
  • 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 ...
  • 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 ...
  • 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. ...
  • 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 ...
  • 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 ...
  • 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 ...
  • 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 ...
  • Avotina, Ye.S.; Kolesnichenko, Yu.A.; van Ruitenbeek, J.M. (Физика низких температур, 2010)
    In this review we present recent theoretical results concerning investigations of single subsurface defects by means of a scanning tunneling microscope (STM). These investigations are based on the effect of quantum ...
