Measuring orbital interaction using quantum information theory

Open access

Abstract

Abstract Quantum information theory gives rise to a straightforward definition of the interaction of electrons Ip,q in two orbitals p,q for a given many-body wave function. A convenient way to calculate the von Neumann entropies needed is presented in this work, and the orbital interaction Ip,q is successfully tested for different types of chemical bonds. As an example of an application of Ip,q beyond the interpretation of wave functions, Ip,q is then used to investigate the ordering problem in the density-matrix renormalization group.

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.
