Nonlocal approximation to the exchange potential and kinetic energy of an inhomogeneous electron gas
Abstract
A nonlocal approximation to the exchange energy and the exchange potential of an inhomogeneous electron gas is presented that is based on the conservation of the main characteristics of the correct Fermi hole. Tested for atoms, it gives better results than the local-density approximation. A new kinetic-energy functional in the Hartree-Fock approximation is also derived that depends explicitly on the exchange-correlation factor. When our nonlocal approximation is used in it, resonable results for the kinetic energy of atoms are obtained.

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
