Low-Temperature Anomaly in the Josephson Critical Current of Junctions in d-Wave Superconductors.
TLDR
The Josephson critical current diverges, formally, in the zero-temperature limit for an ideally specular tunnel barrier with a small transparency, and is shown to be sensitive to the barrier transparency and barrier roughness, which broaden the midgap delta peak in the density of states.

Current-carrying states in Josephson junctions.
TLDR
A unified treatment of clean Josephson junctions, both tunnel junctions and weak links, is developed for the static case and it is found that the energy spectrum depends strongly on the phase difference between the two superconductors.
Superconducting weak links
