Josephson effect in p wave superconductors through dirty normal metals Original Research Article

The Josephson current and its fluctuations through dirty normal metals in p wave superconducting junctions are numerically studied. We discuss effects of a zero-energy state at junction interfaces and those of the proximity effect in normal metals on the Josephson current. An interplay between the two interference effects causes the anomalous current–phase relation in a px wave junctions.
