Libxc: A library of exchange and correlation functionals for density functional theory
Open accessAbstract
Abstract The central quantity of density functional theory is the so-called exchange–correlation functional. This quantity encompasses all non-trivial many-body effects of the ground-state and has to be approximated in any practical application of the theory. For the past 50 years, hundreds of such approximations have appeared, with many successfully persisting in the electronic structure community and literature. Here, we present a library that contains routines to evaluate many of these functionals (around 180) and their derivatives.

Ireland Licensing provisions : GNU Lesser General Public License version 3 No. of lines in distributed program, including test data, etc. : 87455 No. of bytes in distributed program, including test data, etc. : 945365 Distribution format : tar.gz Programming language : C with Fortran bindings. Computer : All. Operating system : All. RAM : N.A. Classification : 7.3, 16.1. Nature of problem : Evaluation of the exchange–correlation energy functional and its derivatives. This is a fundamental part of any atomic, molecular, or solid-state code that uses density-functional theory. Solution method : The values of the energy functional and its derivatives are given in a real grid of mesh points. Running time : Typically much smaller than the remainder of the electronic structure code. The running time has a natural linear scaling with the number of grid points.

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.
