Josephson effect in p wave superconductors through dirty normal metals

摘要

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 p(x) wave junctions. (c) 2005 Elsevier Ltd. All rights reserved.
