Abstract

We propose a model for resonant Josephson tunneling through quantum dots that accounts for Cooper pair-breaking processes in the superconducting leads caused by a magnetic field or spin-flip scattering. The pair-breaking effect on the critical supercurrent I_c and the Josephson current-phase relation I(φ) is largely due to the modification of the spectrum of Andreev bound states below the reduced ...
