The relationship between the density functional Hartree-plus-exchange-correlation potential for an integer N-electron and (N-1)-electron system
arXiv:1107.2488
Abstract
It is shown that the Hartree-plus-exchange-correlation density functional potential for an integer N-electron system differs by a constant form the corresponding potential for an (N-1)-electron system if the densities are determined from the same external potential.
