Mixed quantum–classical dynamics

Tully, John C.·1998·Faraday Discussions

Abstract

We present a unified derivation of the mean-field (Ehrenfest) and surface-hopping approaches to mixed quantum–classical dynamics that elucidates the underlying approximations of the methods and their strengths and weaknesses. We then report a quantitative test of alternative mixed quantum–classical methods against accurate quantum mechanical calculations for a simple one-dimensional curve-crossing model. We conclude that, for this model, surface-hopping with the adiabatic representation is decidedly superior to either mean-field or surface-hopping with the diabatic representation.

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.
