Abstract

The interaction of Wannier excitons with an LO-phonon field is investigated in detail. We derive effective local Hamiltonians which may be used to calculate the whole exciton spectrum in a polarizable medium. The constituents of the exciton are no longer treated as two independent polarons. The coupling of the polarons is described by new displacement amplitudes. The ground-state energy is evaluated variationally as an example and the analytic expression for the exciton's self-energy is discussed as a function of the binding-strength. We do not reproduce numerical results for various materials which have been given in previous letters and have been found to compare satisfactorily with experimental data. Meanwhile our results have been used with great success in a variety of more complex problems due to its formal simplicity and its quantitative accuracy.

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.
