Effective description of hopping transport in granular metals
I. S. Beloborodov, A. V. Lopatin, V. M. Vinokur +1
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 Coulo…
Current-induced magnetization changes in a spin valve due to incoherent emission of non-equilibrium magnons
V. I. Kozub, J. Caro
We describe spin transfer in a ferromagnet/normal metal/ferromagnet spin-valve point contact. Spin is transferred from the spin-polarized device current to the magnetization of the…
1/f noise in hopping conduction: Role of multi-site aggregates
V. I. Kozub, Y. M. Galperin, V. Vinokur
We propose a mechanism for 1/f-type noise in hopping insulators based on the multi-electron charge redistribution within the specific aggregates of the localized states located in…
Charge transfer between a superconductor and a hopping insulator
V. I. Kozub, A. A. Zyuzin, Y. M. Galperin +1
We develop a theory of the low-temperature charge transfer between a superconductor and a hopping insulator. We show that the charge transfer is governed by the coherent two-electr…
AC-Hopping Conductance of Self-Organized Ge/Si Quantum Dot Arrays
Irina L. Drichko, Andrey M. Diakonov, Veniamin I. Kozub +4
Dense ( cm) arrays of Ge quantum dots in Si host were studied using attenuation of surface acoustic waves (SAWs) propagating along the surface of a piezo…
On the theory of thermoelectric phenomena in superconductors
Y. M. Galperin, V. L. Gurevich, V. I. Kozub +1
The theory of thermoelectric effects in superconductors is discussed in connection to the recent publication by Marinescu and Overhauser, Phys. Rev. B 55, 11637 (1997). We argue th…
