Coherence properties of semiconductor quantum dots are of central importance for a variety of applications. Previous studies of decoherence in these systems mainly focused on the interaction with LA phonons, only giving rise to dephasing. In contrast, the interaction with LO phonons additionally causes carrier scattering. To show the importance of the combined influence of dephasing and carrier scattering, we revisit the case of Rabi oscillations in semiconductor quantum dots using a quantum-kinetic treatment of the carrier-LO-phonon interaction.
