Abstract:
The exact electronic ground-state density and external potential are used to improve the accuracy of approximate density functionals. Our approach combines the advantages that the exact exchange-correlation energy functional is more local for full-coupling strength than for the coupling-constant average, and that knowledge of the exact virial can be used to reduce the exchange energy error by a factor of 2.
