31. Note that the expression of shot noise Eq. (10) can be recast in terms of transmission coefficients for each conducting channel [see numerator in Eq. (1)]. Y.-C. Chen and M. Di Ventra (unpublished).
32. ∥ is no longer a good quantum number. We keep this notation for numerical convenience.

41. Note that this result disagrees with the one obtained by Scherbakov et al., Phys. Rev. B 57, 6654 (1998) on quantum wires modeled with hard and soft confining potentials. The main difference being the atomic description of the system in our case, and consequent account of the self-consistent electronic distribution in the wire.
