Quantum decay of the supercurrent and intrinsic capacitance of Josephson junctions beyond the tunnel limit
D. S. Antonenko, M. A. Skvortsov
A nondissipative supercurrent state of a Josephson junction is metastable with respect to the formation of a finite-resistance state. This transition is driven by fluctuations, the…
Keldysh action for disordered superconductors
M. V. Feigel'man, A. I. Larkin, M. A. Skvortsov
Keldysh representation of the functional integral for the interacting electron system with disorder is used to derive microscopically an effective action for dirty superconductors.…
Weak Charge Quantization on Superconducting Islands
M. V. Feigelman, A. Kamenev, A. I. Larkin +1
We consider the Coulomb blockade on a superconductive quantum dot strongly coupled to a lead through a tunnelling barrier and/or normal diffusive metal. Andreev transport of the co…
Density of States in a Mesoscopic SNS Junction
P. M. Ostrovsky, M. A. Skvortsov, M. V. Feigel'man
Semiclassical theory of proximity effect predicts a gap E_g \sim hD/L^2 in the excitation spectrum of a long diffusive SNS junction. Mesoscopic fluctuations lead to anomalously loc…
Hybridization of wave functions in one-dimensional localization
D. A. Ivanov, M. A. Skvortsov, P. M. Ostrovsky +1
A quantum particle can be localized in a disordered potential, the effect known as Anderson localization. In such a system, correlations of wave functions at very close energies ma…
Weak antilocalization in a 2D electron gas with the chiral splitting of the spectrum
M. A. Skvortsov
Motivated by the recent observation of the metal-insulator transition in Si-MOSFETs we consider the quantum interference correction to the conductivity in the presence of the Rashb…
