Temperature-dependent superradiant decay of excitons in small aggregates
Abstract
We investigate the effect of phonons on the cooperative radiative decay of excitons in small aggregates. Our microscopic analysis establishes the existence of a temperature-dependent coherence size, provided the exciton dephasing time scale is much shorter than the fluorescence lifetime ${\mathrm{\ensuremath{\tau}}}_{\mathrm{fl}}$. We calculate the temperature dependenc of ${\mathrm{\ensuremath{\tau}}}_{\mathrm{fl}}$ and use our results to interpret recent photon-echo and fluorescence experiments in strongly coupled J-aggregates of cyanine dye molecules.

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.
