Direct optimization method to study constrained systems within density-functional theory

Wu, Qin, Van Voorhis, Troy·2005·Physical Review A

Abstract

Consider a system with an arbitrary constraint on its electron density (e.g., that there are $N$ charges on a certain group of atoms). We show that in Kohn-Sham density functional theory, the minimum energy state consistent with the constraint is actually a maximum with respect to the constraint potential, and that this solution is unique. This leads us to an efficient algorithm for calculations on constrained systems. Illustrative studies are shown for charge transfer in the zincbacteriochlorin-bacteriochlorin complex, polyene and alkane chains.

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.
