  • Edge states in quantum Hall effect in graphene (Review Article) 
    Gusynin, V.P.; Miransky, V.A.; Sharapov, S.G.; Shovkovy, I.A. (Физика низких температур, 2008)
    We review recent results concerning the spectrum of edge states in the quantum Hall effect in graphene. In particular, a special attention is payed to the derivation of the conditions under which gapless edge states exist ...
  • Effect of next-to-nearest neighbor hopping on electronic properties of graphene 
    Suprunenko, Y.F.; Gorbar, E.V.; Sharapov, S.G.; Loktev, V.M. (Физика низких температур, 2008)
    In the tight-binding approximation, we take into account the next-to-nearest neighbor hopping in graphene that leads to nonrelativistic-like corrections in its low energy spectrum. The electronic density of states in a ...
  • Electron attachment to atomic hydrogen on the surface of liquid ⁴He 
    Arai, T.; Yayama, H.; Kono, K. (Физика низких температур, 2008)
    We demonstrate a possibility that helium surface electrons at cryogenic temperatures can be used as a new source of very low energy electrons. Since both electrons (e¯) and hydrogen atoms (H) are bound on liquid helium ...

    Chaplik, A.V.; Magarill, L.I.; Vitlina, R.Z. (Физика низких температур, 2008)
    In 3D and 2D electronic systems the singular contribution to the static permittivity ε (Kohn singularity) is a small correction to the regular part of ε but it results in the leading term in asymptotic behavior of ...
  • Equations of motions and velocities of longitudinal waves for superfluid ³He–A filled aerogel in the presence 
    Kekutia, Sh.E.; Chkhaidze, N.D. (Физика низких температур, 2008)
    We have determined the dynamic equations for superfluid ³He–A filled aerogel in finite magnetic fields. The speeds of propagating longitudinal modes for this system have been found for A₁ and A phases. We have shown that ...

    Romanovsky, I.A.; Bogachek, E.N.; Krive, I.V.; Landman, U. (Физика низких температур, 2008)
    Superconductivity induced phase-controlled mesoscopic magnetic effects in a two-dimensional electron gas that bridges two superconducting reservoirs are investigated. Giant paramagnetic response of the junction, occuring ...
  • Graphene and graphene-based nanostructures 
    Krive, I.V.; Loktev, V.M.; Shekhter, R.I. (Физика низких температур, 2008)
    This issue of the journal «Fizika Nizkikh Temperatur» is dedicated to the discovery of graphene — a monolayer graphite — in 2004.
  • Growth of ³He crystals at different magnetic fields 
    Bueno, J.; Blaauwgeers, R.; Parshin, A.Y.; Jochemsen, R. (Физика низких температур, 2008)
    The experiments on ³He crystal growth are carried out in magnetic field up 9 T. The data were analyzed and compared with the results found at zero magnetic field. It was found that the interface and the crystal lattice couple ...
  • Index of refraction of a photonic crystal of carbon nanotubes and homogenization of optically anisotropic periodic composites 
    Gumen, L.N.; Krokhin, A.A. (Физика низких температур, 2008)
    We consider the long-wavelength limit for a periodic arrangement of carbon nanotubes. Using the Fourier expansion method we develop an effective-medium theory for photonic crystal of aligned optically anisotropic cylinders. ...

    Avotina, Ye.S.; Kolesnichenko, Yu.A.; van Ruitenbeek, J.M. (Физика низких температур, 2008)
    We have investigated theoretically the conductance of a normal–superconductor point contact in the tunnel limit and analyzed the quantum interference effects originating from the scattering of quasi-particles by point-like ...
  • Interaction of discrete breathers with thermal fluctuations 
    Eleftheriou, M.; Flach, S. (Физика низких температур, 2008)
    Discrete breathers (DB) are time-periodic and spatially localized lattice excitations, which can be linearly stable or unstable with respect to either localized or extended perturbations. We analyze the interaction of ...
