21. The chemical potentials of both superconducting electrodes are set as zero, i.e., (formula presented).

23. In the entire numerical study, we assume that the two dots are identical, although our formula is applicable to general cases.
24. The approximation is expected to be equivalent to a proper truncation of equation of motion, which has been tested in N-CQD-N. SeeC. Niu, L.-J. Liu, andT.-H. Lin, Phys. Rev. B 51, 5130 (1995).
25. Notice that all of the singularities of (formula presented) lie in the lower half-plane.
26. Since (formula presented) and (formula presented) correspond to empty and fully occupied CQDs, they are not typical for a CB valley, and hence the first and fourth peaks in Fig. 22 are not typical for a CB peak.
