  • Shevchenko, S.N. (Физика низких температур, 2009)
    The local quasiparticle density of states in the current-carrying d-wave superconducting structures was studied theoretically. The density of states can be accessed through the conductance of the scanning tunnelling ...
  • Shevchenko, S.N.; Kiyko, A.S.; Omelyanchouk, A.N.; Krech, W. (Физика низких температур, 2005)
    We study the dynamic behavior of a quantum two-level system with periodically varying parameters by solving numerically the master equation for the density matrix. Two limiting cases are considered: multiphoton Rabi ...
  • Kiyko, A.S.; Omelyanchouk, A.N.; Shevchenko, S.N. (2007)
    We study theoretically the behavior of the superconducting flux qubit subjected to the series of the electromagnetic pulses. The possibility of controlling the system state via changing the parameters of the pulse is ...
  • Cherkaskiy, V.A.; Shevchenko, S.N.; Rozhavsky, A.S.; Vagner, I.D. (Физика низких температур, 1999)
    We present a detailed theory of induced persistent current (PC) produced by hyperfine interaction in mesoscopic rings based on a 2 D electron (hole) gas in the absence of external magnetic field. PC emerges due to combined ...
  • Kolesnichenko, Yu.A.; Omelyanchouk, A.N.; Shevchenko, S.N. (Физика низких температур, 2004)
    A stationary Josephson effect in the ballistic contact of two d-wave superconductors with different orientation of the axes and with transport current in the banks is considered theoretically. We study the influence of ...
  • Kolesnichenko, Yu.A.; Shevchenko, S.N. (Физика низких температур, 2005)
    A stationary Josephson effect is analyzed theoretically for a weak link between borocarbide superconductors. It is shown that different models of the order parameter result in qualitatively different current-phase relations.
  • Mahmoodi, R.; Kolesnichenko, Yu.A.; Shevchenko, S.N. (Физика низких температур, 2002)
    A stationary Josephson effect in point contacts between triplet superconductors is analyzed theoretically for most probable models of the order parameter in UPt₃ and Sr₂RuO₄. The consequence of misorientation of crystals ...
  • Shevchenko, S.N.; Omelyanchouk, A.N.; Il'ichev, E. (Физика низких температур, 2012)
    Two basic physical models, a two-level system and a harmonic oscillator, are realized on the mesoscopic scale as coupled qubit and resonator. The realistic system includes moreover the electronics for controlling the distance ...
  • 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 ...
  • Shevchenko, S.N.; Omelyanchouk, A.N. (Физика низких температур, 2006)
    We study the time-averaged upper level occupation probability in a strongly driven two-level system, particularly its dependence on the driving amplitude x₀ and frequency ω and the energy level separation ∆E. In contrast ...
  • Karpov, D.S.; Oelsner, G.; Shevchenko, S.N.; Greenberg, Ya.S.; Il’ichev, E. (Физика низких температур, 2016)
    We study the dynamics of a qubit-resonator system, when the resonator is driven by two signals. The interaction of the qubit with the high-amplitude driving we consider in terms of the qubit dressed states. Interaction ...
