2026-07-072026-07-07http://salesiana.dossiersoluciones.com/handle/123456789/22901The dynamics of an exciton-LO-phonon system after an ultrafast optical excitation in an InAs/GaAs quantum dot is studied theoretically. Influence of anharmonic phonon damping and its interplay with the phonon dispersion is analyzed. The signatures of the zone-edge decay process in the absorption spectrum and time evolution are highlighted, providing a possible way of experimental investigation on phonon anharmonicity effects.10 pages, 2 figuresMesoscale and Nanoscale Physicstext
