Unified scattering approach to Josephson current and thermal noise in BCS and topological superconducting junctions

Abstract : We present a unified description of a junction between s-wave (BCS) superconductors and a junction between p-wave superconductors in a topologically nontrivial phase, which relies on a scattering state expansion. We compute Josephson current and thermal noise in the two kinds of junction and exhibit some characteristic features for a junction of two topological superconductors hosting Majorana zero-energy modes.
