  • 3ω-отклик и времена энергетической релаксации электрон-фононной системы металлической пленки 
    Безуглый, А.И. (Физика низких температур, 2014)
    Переменный ток с частотой приводит к нагреву металлической пленки, осциллирующему с частотой 2ω. При этом вследствие температурной зависимости сопротивления напряжение на пленке имеет V3 -компоненту, которая осциллирует с ...
  • An alternative view at the zero-bias anomaly of metallic point contacts 
    Gloos, Kurt (Физика низких температур, 2009)
    We have studied the zero-bias anomaly of point contacts as function of contact size for a wide range of materials from simple normal metals, superconductors, and magnets to highly correlated heavy-fermion compounds. The ...
  • Andreev-reflection spectroscopy of ferromagnets: the impact of Fermi surface mismatch 
    Tuuli, E.; Gloos, K. (Физика низких температур, 2011)
    We have investigated point contacts between a superconductor (Nb, AuIn2) and a normal metal (ferromagnetic Co, nonmagnetic Cu). The observed Andreev-reflection spectra were analyzed using the modified BTK theory including ...
  • BCS-BEC crossover and nodal points contribution in p-wave resonance superfluids 
    Kagan, M.Yu.; Efremov, D.V. (Физика низких температур, 2009)
    We solve the Leggett equations for BCS–BEC crossover of the resonance p-wave superfluid. We calculate sound velocity, specific heat and the normal density for the BCS-domain (μ > 0), BEC-domain (μ < 0) as well as for the ...

    Khotkevych, N.V.; Kolesnichenko, Yu.A.; van Ruitenbeek, J.M. (Физика низких температур, 2012)
    The conductance of a contact, having a radius smaller than the Fermi wave length, on the surface of a thin metal film is investigated theoretically. It is shown that quantization of the electron energy spectrum in the ...
  • Coulomb blockade of spin-dependent shuttling 
    Park, Hee Chul; Kadigrobov, A.M.; Shekhter, R.I.; Jonson, M. (Физика низких температур, 2013)
    We show that nanomechanical shuttling of single electrons may enable qualitatively new functionality if spin-polarized electrons are injected into a nanoelectromechanical single-electron tunneling (NEM-SET) device. This ...
  • Dendritic flux avalanches in superconducting films 
    Yurchenko, V.V.; Johansen, T.H.; Galperin, Y.M. (Физика низких температур, 2009)
    Thermomagnetic instability in general, and dendritic flux avalanches in particular, have attracted considerable attention of both scientists and engineers working on superconductor applications. Though being harmful for ...
  • Electronic structure, phonon spectra and electron–phonon interaction in ScB₂ 
    Sichkar, S.M.; Antonov, V.N. (Физика низких температур, 2013)
    The electronic structure, Fermi surface, angle dependence of the cyclotron masses and extremal cross sections of the Fermi surface, phonon spectra, electron–phonon Eliashberg and transport spectral functions, temperature ...
  • Fermiology via the electron momentum distribution (Review Article) 
    Kontrym-Sznajd, G. (Физика низких температур, 2009)
    Investigations of the Fermi surface via the electron momentum distribution reconstructed from either angular correlation of annihilation radiation or Compton scattering experimental spectra are presented. The basis of these ...

    The concentration of carriers in LuB₁₂ is evaluated theoretically by applying ab initio FP-LMTO calculations. Theoretical results are found to be in agreement with high precision measurements of the Hall RH(T) coefficient ...
  • Low-energy anomalies in electron tunneling through strongly asymmetric Majorana nanowire 
    Shkop, A.D.; Parafilo, A.V.; Krive, I.V.; Shekhter, R.I. (Физика низких температур, 2016)
    Electron transport through Majorana nanowire with strongly asymmetric couplings to normal metal leads is considered. In three terminal geometry (electrically grounded nanowire) it is shown that the presence of unbiased electrode ...
  • Magnetic-field-induced effects in the electronic structure of itinerant d- and f-metal systems 
    Grechnev, G.E. (Физика низких температур, 2009)
    A paramagnetic response of transition metals and itinerant d- and f -metal compounds in an external magnetic field is studied by employing ab initio full-potential LMTO method in the framework of the local spin density ...

    Bergk, B.; Wosnitza, J. (Физика низких температур, 2009)
    We report systematic de Haas–van Alphen (dHvA) investigations in the normal and superconducting state of RNi₂B₂C (R = Y and Lu). The observed rich frequency spectrum of the dHvA signals results from a rather complex ...
  • Mixed 1D–2D quantum electron transport in percolating gold film 
    Beliaye, E.Yu.; Belevtsev, B.I.; Kolesnichenko, Yu.A. (Физика низких температур, 2011)
    The gold film (mean thickness ≈ 3.5 nm) was condensed in high vacuum at temperature 70 K on single-crystal sapphire substrate. The transport properties of the film at low temperature reveal simultaneously indications of ...

    Shekhter, Robert I.; Santandrea, Fabio; Sonne, Gustav; Gorelik, Leonid Y.; Jonson, Mats (Физика низких температур, 2009)
    Strong coupling between electronic and mechanical degrees of freedom is a basic requirement for the operation of any nanoelectromechanical device. In this Review we consider such devices and in particular investigate the ...
  • On the limits of application of Anderson and Kondo models in physics of strongly correlated electron systems 
    Sluchanko, N.E. (Физика низких температур, 2015)
    We argue that the Anderson and Kondo models turn out to be irrelevant for the description of some strongly correlated electron systems and suggest the mechanism for the formation of many-body states (heavy fermions) being ...
