Functional relations for the density functional exchange and correlation functionals connecting functionals at three densities
Daniel P. Joubert
It is shown that the DFT exchange and correlation functionals satisfy an expression that couples exchange and correlation functionals and functional derivatives evaluated at three…
Identity for the second functional derivative of the density functional Hartree plus exchange-correlation functional
Daniel P. Joubert
It is shown that the integral of the product of the charge density difference of the N- and (N-1)-electron densities of the same Hamiltonian and the second functional derivative of…
Identity for the DFT correlation functional
Daniel P. Joubert
It is shown that the electron density functional correlation functional satisfies an equation that links the N-electron and (N-1)-electron densities of the same adiabatically scale…
Identities for density functionals linking functionals of different densities
Daniel P. Joubert
In electron density functional theory formal properties of density functionals play an important role in constructing and testing approximate functionals. In this paper it is shown…

Daniel P. Joubert
The electron-electron mutual Coulomb repulsion energy density functional satisfies an equation that links functionals and functional derivatives at N-electron and (N-1)-electron de…
The relationship between the density functional Hartree-plus-exchange-correlation potential for an integer N-electron and (N-1)-electron system
Daniel P. Joubert
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 (…
