Reply to Comment on "Dynamical corrections to the DFT-LDA electron conductance in nanoscale systems"

TL;DR

This paper defends the significance of viscosity corrections in nanoscale conductance calculations, arguing that more precise modeling could reveal larger effects than previously suggested.

Contribution

It clarifies that viscosity corrections to electron conductance are potentially substantial and depend on detailed electronic modeling, countering prior comments suggesting they are negligible.

Findings

Viscosity corrections may be larger in realistic systems.

More accurate density and current density modeling is necessary.

The importance of electronic correlations is emphasized.

Abstract

We reply to the comment by Jung, Bokes, and Godby (arXiv:0706.0140) on our paper Phys. Rev. Lett. 94, 186810 (2005). We show that the results in their comment should not be taken as an indication that the viscosity corrections to the conductance of real nanoscale structures are small. A more accurate treatment of the density and current density distribution and of the electronic correlations may yield much larger corrections in realistic systems.
