Title says it all. I find it amazing that QED can explain so much, and physicists(myself included) seem arrogant in its predictive power, yet I still don't see how it explains superconductivity.

Things like the supercurrent, two electrons travel together in superconductors instead of the usual one at a time.

And the fact that a DC potential across superconductors can create an oscillating current.

And then there's type I vs type II superconductors. Does QED help explain why one type excludes magnetic fields completely, and the other type allows the field to pass in filaments.

Has the application of QED to superconductivity had success?
