    Lopatin, A.V.
    We present a unified description of the low-temperature phase of granular metals that reveals a striking generality of the low-temperature behaviors. Our model explains the universality of the low-temperature conductivity that coincides exactly with t . . .

    Article
    Beloborodov, Igor S.
    We develop a theory of a variable range hopping transport in granular conductors based on the sequential electron tunnelling through many grains in the presence of the strong Coulomb interaction. The processes of quantum tunnelling of real electrons a . . .

    Efetov, K.B.
    We investigate transport in a granular metallic system at large tunneling conductance between the grains, gT>>1. We show that at low temperatures, T<=gTd, where d is the single mean energy level spacing in a grain, the coherent electron motion at larg . . .

    Beloborodov, Igor S.
    We investigate the suppression of the superconducting transition temperature due to Coulomb repulsion in granular metallic systems at large tunneling conductance between the grains, gT>>1. We find the correction to the superconducting transition tempe . . .

    Beloborodov, Igor S.
    We investigate the suppression of superconducting transition temperature in granular metallic systems due to (i) fluctuations of the order parameter (bosonic mechanism) and (ii) Coulomb repulsion (fermionic mechanism) assuming large tunneling conducta . . .

    Fazio, Rosario
    We study the electron thermal transport in granular metals at large tunnel conductance between the grains, gT>>1 and not too low a temperature T>gTd, where d is the mean energy level spacing for a single grain. Taking into account the electron-electro . . .

    Lopatin, A.V.
    We investigate effects of Coulomb interaction and hopping transport in the insulator phase of granular metals and quantum dot arrays considering both spatially periodic as well as irregular grain or dot arraignments. We study the Mott transition betwe . . .

    Vinokur, V.M.
    We analyze the possibility of the formation of a magnetic-field-induced insulating state in a two-dimensional granular superconductor with relatively strong intergranular coupling and show that such a state appears in a model with spatial variations o . . .

    Beloborodov, Igor S.
    We investigate the effect of Coulomb interactions on the tunneling density of states (DOS) of granular metallic systems at the onset of Coulomb blockade regime in two and three dimensions (d=2,3). Using the renormalization group technique we derive th . . .
