Hall Effect in Granular Metals: Weak Localization Corrections
Maxim Yu. Kharitonov, Konstantin B. Efetov
We study the effects of localization on the Hall transport in a granular system at large tunneling conductance corresponding to the metallic regime. We show that the f…
Charge accumulation at the boundaries of a graphene strip induced by a gate voltage: Electrostatic approach
P. G. Silvestrov, K. B. Efetov
Distribution of charge induced by a gate voltage in a graphene strip is investigated. We calculate analytically the charge profile and demonstrate a strong(macroscopic) charge accu…
Hall Transport in Granular Metals and Effects of Coulomb Interactions
Maxim Yu. Kharitonov, Konstantin B. Efetov
We present a theory of Hall effect in granular systems at large tunneling conductance . Hall transport is essentially determined by the intragrain electron dynamics, wh…
Nonhomogeneous magnetization and superconductivity in superconductor-ferromagnet structures
F. S. Bergeret, A. F. Volkov, K. B. Efetov
We study two different superconductor-ferromagnet (S/F) structures. We consider first a Josephson junction which consists of two S/F bilayers separated by an insulating layer. We s…
Electromagnetic field induced suppression of transport through - junctions in graphene
M. V. Fistul, K. B. Efetov
We study quasi-particle transmission through an - junction in a graphene irradiated by an electromagnetic field (EF). In the absence of EF the electronic spectrum of undoped…
