    Article
    Beloborodov, Igor S.
    We study the electron transport in semiconducting nanocrystal arrays at temperatures T<<Ec, where Ec is the charging energy for a single grain. In this temperature range, the electron transport is dominated by cotunneling processes. We discuss both el . . .

    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 . . .

    Chtchelkatchev, N.M.
    We study heating effects in a chain of weakly coupled grains due to electron-hole pair creation. The main mechanism for the latter at low temperatures is due to inelastic electron cotunneling processes in the array. We develop a quantitative kinetic t . . .

    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 . . .

    Glatz, A.
    We investigate the quantum heat exchange between a nanojunction and a many-body or electromagnetic environment far from equilibrium. It is shown that the two-temperature energy emission-absorption mechanism gives rise to a giant heat flow between the . . .

    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 . . .

    Glatz, A.
    We study the giant magnetoresistance of nanogranular magnets in the presence of an external magnetic field and finite temperature. We show that the magnetization of arrays of nanogranular magnets has hysteretic behaviour at low temperatures leading to . . .
