    • Alternatively, one can characterize the magnitude of current deviations by the current [formula omitted] at which the differential conductance [formula omitted] is minimum (“inflection point”). Roughly, [formula omitted] and G are related as follows: [formula omitted] where [formula omitted] is the voltage scale of the I-V curve.

    • Q-MQT current in the N-junction pump was calculated in Ref. 10 for [formula omitted] [formula omitted] and [formula omitted] In this case only one Q-MQT process [formula omitted] occurs. Here we generalize these calculations to the nonvanishing T, V, and [formula omitted] Note, however, that our results for [formula omitted] [formula omitted] and [formula omitted] differ slightly from those of Ref. 10. In particular, the current given by Eqs. (39) and (46) for [formula omitted] is larger than the upper bound found in Ref. 10. This difference stems from differences in calculation of transition matrix elements S [Eq. (46)] and estimation of integrals in Eq. (39). We think that our results are correct.
