Abstract

Soft, fully separable ab initio pseudopotentials, introduced some years ago by Kleinman and Bylander [Phys. Rev. Lett. 48, 1425 (1982)], have proven to be very useful for large-scale electronic-structure and total-energy calculations. However, these pseudopotentials can induce unphysical results and destroy important chemical properties of the atom in the solid, if not constructed cautiously. We present here a detailed analysis of Kleinman-Bylander separable pseudopotentials. Two different techniques (a spectral investigation, and the logarithmic-derivative construction) allow a deeper understanding of their properties. It is shown how the above-mentioned problems can be avoided.

Recomputing p-values needs the paper’s full text.

Claims the paper makes

We couldn’t retrieve this paper’s full text, so its claims and self-check weren’t run. The registry and citation checks still apply.

Claims other papers make about this one

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.
