Coexistence of localized and extended states in the Anderson model with long-range hopping
V. Temkin, A. S. Ioselevich
We study states arising from fluctuations in the disorder potential in systems with long-range hopping. Here, contrary to systems with short-range hopping, the optimal fluctuations…
Two-impurity scattering in quasi-one-dimensional systems
A. S. Ioselevich, N. S. Peshcherenko
In a quasi-one-dimensional system (a tube) with low concentration of defects the resistivity has peaks (van-Hove singularities) as a function of Fermi-energy. We show that…
Non-Born effects in scattering of electrons in a conducting strip with low concentration of impurities
N. S. Peshcherenko, A. S. Ioselevich
We extend the theory of non-Born effects in resistivity of clean conducting tubes (developed in our previous work arXiv:1810.00426) to ``strips'' -- quasi-one-dimensional struc…
Non-Born effects in scattering of electrons in a clean conducting tube
A. S. Ioselevich, N. S. Peshcherenko
Quasi-one-dimensional systems demonstrate Van Hove singularities in the density of states and the resistivity , occurring when the Fermi level crosses a bottom o…
Cotunnelling and polaronic effect in granular systems
A. S. Ioselevich, V. V. Sivak
We theoretically study the conductivity in arrays of metallic grains due to the variable-range multiple cotunneling of electrons with short-range (screened) Coulomb interaction. Th…
Percolation with excluded small clusters and Coulomb blockade in a granular system
A. S. Ioselevich, D. S. Lyubshin
We consider dc-conductivity of a mixture of small conducting and insulating grains slightly below the percolation threshold, where finite clusters of conducting grains are char…
