    • The "Mott" in the name "doped D-Mott phase" is not meant to imply that the phase that results when doping the D-Mott phase is necessarily insulating. Whether or not the various rationally doped phases are insulating is one of the central questions discussed in this paper

    • F = 2pi;(1 - δ) is expected to be exact. This suggests that the conclusions regarding the basic-Umklapp interaction should hold more generally. This should also include the order-of-magnitude estimate 1/δ for the length scale signifying the crossover from insulating behavior at shorter length scales to metallic behavior at longer length scales

    • We note that by choosing a much smaller value of the fitting parameter b in Fig. 17, the fit of the current could have been much improved, but the density oscillations in the analytical curve would have been smaller than in the numerical curve, which would not be consistent with our picture of the role of quantum fluctuations
