FIG. 1. Sketch of a typical mesoscopic system: a central interacting region (red) is connected to several (semi-infinite) non-interacting electrodes (blue) with finite temperatures T i
FIG. 4. Same parameters as in Fig. 3 but the integrand has now been summed over Keldysh indices
FIG. 5. Same parameters as in Fig. 3 but the integrand now uses the matrix P 2 instead of M 2 , i.e
Fig. 6 shows the Q n for n up to n = 15 as well as the corresponding c n and s n . We find that the magnitudes of the Q n do not appear to decrease with n but rather  re-main of order unity |Q n | ≈ 1
