Effective spin-flip scattering in diffusive superconducting proximity systems with magnetic disorder
D. A. Ivanov, Ya. V. Fominov, M. A. Skvortsov +1
We revisit the problem of diffusive proximity systems involving superconductors and normal metals (or ferromagnets) with magnetic disorder. On the length scales much larger than it…
Dyson-Maleev representation of nonlinear sigma-models
D. A. Ivanov, M. A. Skvortsov
For nonlinear sigma-models in the unitary symmetry class, the non-linear target space can be parameterized with cubic polynomials. This choice of coordinates has been known previou…
Mesoscopic fluctuations of the supercurrent in diffusive Josephson junctions
M. Houzet, M. A. Skvortsov
We study mesoscopic fluctuations and weak localization correction to the supercurrent in Josephson junctions with coherent diffusive electron dynamics in the normal part. Two kinds…
Local correlations of different eigenfunctions in a disordered wire
M. A. Skvortsov, P. M. Ostrovsky
We calculate the correlator of the local density of states <ρ_{E}(r_1)ρ_{E+ω}(r_2)> in quasi-one-dimensional disordered wires in a magnetic field, assuming that |r_1-r_2| is much s…
Dephasing in disordered metals with superconductive grains
M. A. Skvortsov, A. I. Larkin, M. V. Feigel'man
Temperature dependence of electron dephasing time is calculated for a disordered metal with small concentration of superconductive grains. Above the macroscopic supercondu…
Coulomb Blockade of Proximity Effect at Large Conductance
P. M. Ostrovsky, M. A. Skvortsov, M. V. Feigel'man
We consider the proximity effect in a normal dot coupled to a bulk superconducting reservoir by the tunnel contact with large normal conductance. Coulomb interaction in the dot sup…
