    • Strictly speaking, the overlap should include a core contribution for Vanderbilt pseudopotentials. but the dot product of the orbitals provide a sufficiently accurate description for this purpose.

    • Although in Ref. 24 the method is referred to as "first-principles" molecular dynamics (with quotation marks included), such a characterization is at odds with accepted terminology. The approach actually relies on a combination of empirical and semiempirical methods, with restricted Hantee-Fock self-consistent field (SCF) calculations of certain portions of the simulation. In addition, for the SCF, whose accuracy has been shown on numerous occasions to be substantially less than that of gradient corrected density functional theory, it is unclear how the forces were calculated for the dynamics. It would appear that they were obtained from empirical potentials using partial charges obtained by population analysis, an approach which, in light of the ab initio MD simulation methods available today, would not be considered to be first-principles MD.

    • Price and Halley (Ref. 27) have simulated a modelistic metal/water interface using a one-electron "metal" and an empirical, non-first-principles, model for water. While such a generic approach has some features in common with a real metal/water interface, there are many other features which have been neglected.
