Abstract

Spatial dependences of the pair potential in normal metal/insulator/p-wavesuperconductor junctions are determined self-consistently. Pair potentialshave strong spatial dependences near the interface depending on the magnitude of the transparency of the junctions. In this paper, we demonstrate that subdominant s-wave, component of the pair potential can mix near the interface, which breaks the time reversal symmetry, with the introduction of the additional s-wave attractive potential even in the triplet superconductor. In a promising pair potential in the superconducting state of Sr2RnO4, s-wave component does not appear although zero-energy state (ZES) exists. This result indicates that the existence of the ZES does not induce the s-wavecomponent near the interface, where ZES is only formed by a quasiparticle injected perpendicularly to the interface.
