We investigate the suppression of the proximity effect in mesoscopic normal metal/superconductor systems induced by Coulomb interaction. We identify and elucidate the mechanism by which disorder leads to an amplification of this effect. In particular, for strong enough disorder, the proximity effect is shown to vanish. An expression for the tunneling density of states is obtained, and experimental applications are discussed.

On the conductance oscillations in a mesoscopic proximity system
A fork-shaped N-branch Andreev interferometer is considered and the conductance of the system is calculated as a function of the phase difference in the superconducting order parameters across the
Dephasing in disordered metals with superconductive grains.
TLDR
In a broad temperature range tau(-1)(phi)(T) strongly exceeds the prediction of the classical theory of dephasing in normal disordered conductors, whereas magnetoresistance is dominated (in two dimensions) by the Maki-Tompson correction and is positive.
Gate-Controlled Superconducting Proximity Effect in Carbon Nanotubes.
TLDR
The superconducting proximity effect in single-walled carbon nanotubes connected to niobium electrodes was controlled with the use of nearby gates that tune the niobia-nanotube transparency with a dip in the low-bias differential resistance, indicating a proximity effect mediated by Andreev reflection.
Critical behavior of density of states near Fermi energy in low-dimensional disordered metals
We study the effect of electron-electron interaction on the one-particle density of states (\emph{DOS}) $\rho^{(d)}(\epsilon,T)$ of low-dimensional disordered metals near Fermi energy within the
A review of weak/strong links and junctions in high-Tc superconductors as a transition to a Mott insulator
In high-Tc superconductors (HTS), which are layered, doped Mott insulators, weak links occur easily in preparation and growth, being weakened further by irradiation, by impurities and by disorder.

It is shown that the temperature of the resistive transition $T_r$ of a superconducting film can be increased by a thin superconducting or normal overlayer. For instance, deposition of a highly
Quantum disorder and quantum chaos in Andreev billiards
We investigate the crossover from the semiclassical to the quantum description of electron energy states in a chaotic metal grain connected to a superconductor. We consider the influence of
