All-electron and pseudopotential force calculations using the linearized-augmented-plane-wave method

Yu, Rici, Singh, D., Krakauer, H.·1991·Physical Review B

Abstract

All-electron and pseudopotential formulations for atomic forces in the linear-augmented-plane-wave (LAPW) method within the local-density approximation are presented. Due to the fact that the basis functions in the LAPW method (and in other linear muffin-tin-orbitals-based methods) have discontinuous second derivatives across the muffin-tin sphere boundaries, a large surface contribution to the incomplete-basis-set corrections to the Hellmann-Feynman force is shown to exist. The formulations are applied to frozen-phonon calculations in semiconductor, transition-metal, and noble-metal systems. The results are in excellent agreement with total-energy calculations and experiment.

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.
