  • Boundary friction on molecular lubricants: rolling mode? 
    Loktev, V.M.; Pogorelov, Yu.G. (Физика низких температур, 2004)
    A theoretical model is proposed for low-temperature friction between two smooth rigid solid surfaces separated by lubricant molecules, admitting their deformations and rotations. The appearance of different modes of ...
  • Conventional and unconventional impurity effects in superconductors 
    Pogorelov, Yu.G.; Loktev, V.M. (Физика низких температур, 2018)
    A survey is done on the effects of impurities in different types of superconductors, both conventional and unconventional, on their electronic spectra and physical properties. These effects can be generally divided on the ...
  • Effect of electron-magnon coupling on the electronic spectrum of weakly doped high-Tc compounds 
    Ivanov, M.A.; Loktev, V.M.; Pogorelov, Yu.G. (Физика низких температур, 1998)
    A theoretic analysis of magnon-induced damping Г of quasiparticle states in the normal phase of doped copper-oxide high-Tc materials is developed, based on a microscopic model which accounts for the specific 2D structure ...
  • Formation of d-wave superconducting order in a randomly doped lattice 
    Loktev, V.M.; Pogorelov, Yu.G. (Физика низких температур, 2001)
    We consider the interplay between superconducting coupling and dopant impurity scattering of charge carriers in planar square lattice systems and examine the physical conditions (doping level, temperature, local ...
  • Impurity and vacancy effects in graphene 
    Loktev, V.M.; Pogorelov, Yu.G. (Физика низких температур, 2012)
    A Green function analysis has been developed for quasiparticle spectrum of a 2D graphene sheet in presence of different types of substitutional disorder, including vacancies. The anomalous character of impurity effects ...
  • Impurity effects in quasiparticle spectrum of high-Tc superconductors 
    Pogorelov, Yu.G.; Santos, M.C.; Loktev, V.M. (Физика низких температур, 2011)
    The revision is made of Green function methods that describe the dynamics of electronic quasiparticles in disordered superconducting systems with d-wave symmetry of order parameter. Various types of impurity perturbations ...
  • Magnetic properties of amorphous Co₀.₇₄Si₀.₂₆/Si multilayers with different number of periods 
    Kakazei, G.N.; Santos, N.M.; Quiros, C.; Velez, M.; Martin, J.I.; Alameda, J.M.; Golub, V.O.; Saliuk, O.Y.; Pogorelov, Yu.G.; Carmo, M.C.; Sobolev, N.A.; Sousa, J.B. (Физика низких температур, 2010)
    Two sets of [Co₀.₇₄Si₀.₂₆0.26(5 nm)/Si(s)]n amorphous films were prepared by magnetron sputtering: one in the form of multilayers with the Si spacer thickness s fixed at 3 nm, and the number of periods n varying from 1 to ...
