  • Disorder effect on the density of states in Landau quantized graphene 
    Dóra, Balázs (Физика низких температур, 2008)
    We have studied the effect of gaussian potential (on-site) and unidirectional bond disorder on the density of states (DOS) of Landau quantized graphene. The broadening of the Landau levels weakly depends on energy and ...
  • 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 ...
  • Spectral function of graphene with short-range impurity centers 
    Skrypnyk, Yu.V.; Loktev, V.M. (Физика низких температур, 2008)
    Spectral function of graphene with point substitutional defects is calculated for different impurity concentrations. It is demonstrated that features in the spectral function of graphene observed in ARPES experiments can ...
  • The Berry phase in graphene and graphite multilayers 
    Mikitik, G.P.; Sharlai, Yu.V. (Физика низких температур, 2008)
    We discuss the electron energy spectra and the Berry phases for graphene, a graphite bilayer, and bulk graphite allowing for a small spin-orbit interaction. If an electron orbit in the Brillouin zone surrounds several Dirac ...
  • Tight-binding study of nonmagnetic-defect-induced magnetism in graphene 
    Kumazaki, H.; Hirashima, D.S. (Физика низких температур, 2008)
    This review describes a study of nonmagnetic-defect-induced magnetism of graphene on the basis of a tight-binding model. A vacancy induces a quasilocalized impurity state at the chemical potential around itself, and it ...
  • Toward theory of quantum Hall effect in graphene 
    Gorbar, E.V.; Gusynin, V.P.; Miransky, V.A. (Физика низких температур, 2008)
    We analyze a gap equation for the propagator of Dirac quasiparticles and conclude that in graphene in a magnetic field, the order parameters connected with the quantum Hall ferromagnetism dynamics and those connected ...
  • Vacuum polarization in graphene with a topological defect 
    Sitenko, Yu.A.; Vlasii, N.D. (Физика низких температур, 2008)
    The influence of a topological defect in graphene on the ground state of electronic quasiparticle excitations is studied in the framework of the long-wavelength continuum model originating in the tightbinding approximation ...
