Query: Minigap in a long disordered SNS junction: analytical results   We review and refine analytical results on the density of states in a long
disordered superconductor - normal-metal - superconductor junction with
transparent interfaces. Our analysis includes the behavior of the minigap near
phase differences zero and PI across the junction, as well as the density of
states at energies much larger than the minigap but much smaller than the
superconducting gap.
