|
| The present authors have given an exact theory of the exchange-correlation potential V-xc(r) in terms of (i) the exact ground-state electron density n(r) and (ii) the idempotent Dirac density matrix gamma(r,r') generated by the DFT one-body potential V(r), having n(r) as its diagonal element. Here, we display two approximate consequences: (a) a form of V-xc(r) generated by the semiempirically fine-tuned HF density of Cordero et al. (N.A. Cordero, N.H. March, and J.A. Alonso, Phys. Rev. A 75, 052502 (2007)) and (b) the exchange-only potential V-x(r) determined solely by the HF ground state density for the Be atom. | | |
