✦ Synopsis

The correlation holes for densities of equal and opposite spin around a test electron are determined from the Schrodinger Γ«quation with proper boundary conditions. The traditional 'exchange' term follows from the boundary condition which respects a spacial exclusion principle for equal spins. The resulting potential compares reasonably well with standard local density potentials and the approach is feasible for extensions towards non-local effects.

Several different versions of density functional theory (DFT) that satisfy Hohenberg-Kohn theorems are characterized by different definitions of a reference or model state determined by an N-electron ground state. A common formalism is developed in which exact Kohn-Sham equations are derived for sta
