7. Folk et al. (Ref. 4) interpret their data in terms of the dephasing rate (Formula presented) but we would argue that their experiment is more sensitive to the inelastic scattering rate (Formula presented) than to (Formula presented) It is inelastic scattering that destroys the (Formula presented)-enhancement of the conductance peaks — not dephasing. Indeed, the theories of Refs. 456 use a model of “sequential tunneling,” in which there is no phase coherence at all between the electron entering and leaving the quantum dot. It is irrelevant for the (Formula presented)-enhancement whether such phase coherence exists or not. One can conclude from the experimental data that (Formula presented), but the relative magnitude of (Formula presented) and (Formula presented) remains undetermined.
