Abstract

We investigate electron transport through quantum dot in the Kondo regime with p-wave superconducting leads when T_K>Δ. The current and the shot-noise power are calculated as functions of the applied voltage in the sub-gap region eV<Δ. In addition, the Josephson current is calculated as function of temperature and phase. We point out the qualitative difference between junctions with s-wave and p-wave superconducting leads.
