Abstract

Popular modern generalized gradient approximations are biased toward the description of free-atom energies. Restoration of the first-principles gradient expansion for exchange over a wide range of density gradients eliminates this bias. We introduce a revised Perdew-Burke-Ernzerhof generalized gradient approximation that improves equilibrium properties of densely packed solids and their surfaces.

Each is checked against this paper’s own text: does it say what the citing paper says it does?

  • The majority of excited-state calculations are based on many-body perturbation theory (e.g., G0W0, self-consistent GW, BSE, DMFT) and are performed on top of a DFT calculation, which provides the starting point.

    “The majority of excited-states calculations are based on many-body perturbation theory (MBPT), e.g. G 0 W 0 and self-consistent GW [31-33], the Bethe-Salpeter equation (BSE) [34], or dynamical mean field theory (DMFT) [35], and are performed on-top of a DFT calculation, which provides the starting point for both self-consistent and one-shot approaches.”

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.
