A microscopic derivation of the Josephson effect It is a little bit surprising to me that it seems hard to find a detailed, microscopic derivation of the Josephson effect. Generally, you see a hand-waving derivation based on the macroscopic coherence theory (or assumption). 
So, could anyone point a relevant paper to me? 
I know the paper by Cohen, Falicov, and Phillips, but I cannot make sense of it. 
 A: As far as I remember, the paper you cite (let me give the full reference)

is about tunneling effect between two superconductors. The Josephson effect is not discussed in this paper, for the simple reason Josephson didn't published his papers at the time of the above paper ... 
Perhaps the Josephson effect was first microscopically calculated by Josephson himself ... What about

What do you call microscopic ? Calculating from the tunneling Hamiltonian, or from conservation of the current and overlapping Green's function isn't sufficient for you ? 
If you're looking for a textbook, then the tunneling calculation, originated in
