a Numerical Study of Josephson Current in P Wave Superconducting Junctions

We numerically study the Josephson current and its fluctuations through dirty normal metals in p wave superconducting junctions. Effects of a zero-energy state at junction interfaces and the proximity effect in normal metals on the Josephson effect are discussed. An interplay between the two effects drastically enhances the Josephson current and suppresses its fluctuations in a p_x wave symmetry.
