The Josephson effects in weakly coupled superconductors
TLDR
In this article, the effects described arise as a consequence of two terms calculated by Josephson in the expression for the electrical current flowing between a pair of weakly coupled superconductors.Abstract:
The effects described arise as a consequence of two terms calculated by Josephson in the expression for the electrical current flowing between a pair of weakly coupled superconductors. One of these terms is present at zero voltage and represents a supercurrent which can cross such barriers as thin layers of insulator or normal metal; the other is an extra component of resistive current. The review sets out sufficient theoretical background to allow readers with no previous knowledge of superconductivity to understand the basic physics of the effects. It also caters for those wishing to learn enough to understand devices based on Josephson effects. The article concentrates on fundamentals, and early and recent experimental and theoretical developments in the understanding of Josephson weak links of all types are emphasized.read more

Increased resistance below the superconducting transition in granular metals
TL;DR: In this article, the authors show that granular metal systems can show an increased electrical resistance when the metal in the grains becomes superconducting, which is explained quantitatively on the assumption that charge is transferred between grains by tunnelling of quasiparticles.

Theory of Superconductivity
TL;DR: In this article, a theory of superconductivity is presented, based on the fact that the interaction between electrons resulting from virtual exchange of phonons is attractive when the energy difference between the electrons states involved is less than the phonon energy, and it is favorable to form a superconducting phase when this attractive interaction dominates the repulsive screened Coulomb interaction.

TL;DR: In this article, it was shown that there exist effects of potentials on charged particles, even in the region where all the fields (and therefore the forces on the particles) vanish.
