  • Density of states of Dirac–Landau levels in a gapped graphene monolayer under strain gradient 
    Shubnyi, V.O.; Sharapov, S.G. (Физика низких температур, 2017)
    We study a gapped graphene monolayer in a combination of uniform magnetic field and strain-induced uniform pseudomagnetic field. The presence of two fields completely removes the valley degeneracy. The resulting density ...
  • 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 ...
  • Entropy per particle spikes in the transition metal dichalcogenides 
    Shubnyi, V.O.; Gusynin, V.P.; Sharapov, S.G.; Varlamov, A.A. (Физика низких температур, 2018)
    We derive a general expression for the entropy per particle as a function of chemical potential, temperature and gap magnitude for the single layer transition metal dichalcogenides. The electronic excitations in these ...
  • Impurity induced broadening of Drude peak in strained graphene 
    Shubnyi, V.O.; Sharapov, S.G.; S.G., Y.V. (Condensed Matter Physics, 2018)
    The recent experimental study of the far-infrared transmission spectroscopy of monolayer graphene has shown that the Drude peak width increases by more than 10% per 1% of applied mechanical strain, while the Drude weight ...
  • Optical-conductivity sum rule in cuprates and unconventional charge density waves: a short review 
    Benfatto, L.; Sharapov, S.G. (Физика низких температур, 2006)
    We begin with an overview of the experimental results for the temperature and doping dependences of the optical-conductivity spectral weight in cuprate superconductors across the whole phase diagram. Then we discuss ...
  • Phase fluctuations and pseudogap properties: influence of nonmagnetic impurities 
    Loktev, V.M.; Quick, R.M.; Sharapov, S.G. (Физика низких температур, 2000)
    The presence of nonmagnetic impurities in a 2D “bad” metal depresses the superconducting Berezinskii–Kosterlitz–Thouless transition temperature while leaving the pairing energy scale unchanged. Thus the region of the ...
  • Quantum oscillations as the tool for study of new functional materials (Review Article) 
    Gusynin, V.P.; Loktev, V.M.; Luk’yanchuk, I.А.; Sharapov, S.G.; Varlamov, A.A. (Физика низких температур, 2014)
    We present an overview of our recent results on quantum magnetic oscillations in new functional materials. We begin with the Lifshitz and Kosevich approach for quasi-2D layered materials and obtain general formulas for the ...
  • Spin Nernst effect and intrinsic magnetization in two-dimensional Dirac materials 
    Gusynin, V.P.; Sharapov, S.G.; Varlamov, A.A. (Физика низких температур, 2015)
    We begin with a brief description of the role of the Nernst–Ettingshausen effect in the studies of the hightemperature superconductors and Dirac materials such as graphene. The theoretical analysis of the NE effect is ...
  • Valentin Peschansky and puzzles of magnetotransport 
    Slobodeniuk, A.O.; Sharapov, S.G.; Loktev, V.M. (Физика низких температур, 2011)
    We study two-dimensional electronic gas (2DEG) in the background of the Aharonov–Bohm and constant magnetic fields. The problem of ambiguity of the solutions of the Schrödinger equation is investigated by introducing a ...
