    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 ...
  • Gamayun, O.V.; Gorbar, E.V.; Gusyn, V.P. (2010)
    We analyze the excitonic instability in graphene by solving the Bethe–Salpeter equation for the electron-hole bound state. In the supercritical regime, we show that this equation has a tachyon in its spectrum. We argue ...
  • 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 ...
