2. O. Gunnarsson, M. Jonson, and B. I. Lundqvist, Phys. Rev. B 20, 3136 (1979), on page 3154, it is argued that at points far outside a metal surface (large z) the KS potential decays faster than - e 2 / z when only exchange effects are included. 10.1103/PhysRevB.20.3136
3. C.-O. Almbladh and U. von Barth, Phys. Rev. B 31, 3231 (1985), on page 3236, it is argued that for macroscopic systems the exchange potential tends exponentially to zero, concluding that long-range components of V x c (z) can only originate from correlation effects. 10.1103/PhysRevB.31.3231
4. L. J. Sham, Phys. Rev. B 32, 3876 (1985), by analyzing the asymptotic limit of the so-called Sham-Schlüter integral equation for V x c (z), it is concluded that the exchange potential at points far outside a metal surface is of the form ∼ - e 2 / z 2, in disagreement with Ref.. 10.1103/PhysRevB.32. 3876
