    • We would like to thank Professor Sadamichi Maekawa for bringing this reference to our attention. This is true if one calculates the total two point conductivity. Instead, in this paper we only consider the subset of diagrams that corresponds to the short range part (governed by the elastic mean free paths) and that yields the Boltzmann conductivity in the limit kF λ gg 1 [see, ]. Actually, there exist extra ladder diagrams (which we have neglected) that lead to a long range contribution associated with diffusion processes and such that the total conductivity is divergenceless. However, the global conductance calculated with our short range conductivity and fields subject to the constraints (25) is the same as the true global conductance calculated with the total conductivity but with arbitrary fields. These results will be discussed in a forthcoming publication.
