Exact exchange-correlation potential of an ionic Hubbard model with a free surface
In Kohn-Sham density functional theory (DFT) the interacting electron problem is mapped into a noninteracting problem in an effective potential v(KS). It is known that the charge gap of the interacting system is different from the gap of the effective problem due to a jump Δ(xc) in v(KS) when an ele...
