A Note on the Propagation of Excitation in an Idealized Crystal
Abstract
It is shown that, in insulators, overlapping of the electronic wave functions of near-by crystal constituents is not necessary for effective transfer of excitation energy by the "exciton" mechanism. The electromagnetic interaction of the "virtual" dipoles of the transition is sufficient to give rise to such transfer characterized in cubic crystals by a wave number k, and an anisotropic effective mass, given in order of magnitude by the ratio electronic mass/oscillator strength of transition. Implications and limitations of the calculation are discussed.

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.
