• We report on the magnetooptical evidence and theoretical modelling of polaron effects in semiconductor quantum dots. We show that polaron couplings lead to very large anticrossings in the far infrared magnetoabsorption transitions. A modelling of polaron levels by diagonalization of a Fröhlich Hamiltonian between uncoupled electron–Longitudinal Optical phonon states is in excellent agreement with experiments. A theoretical study of the polaron relaxation by means of the couplings to the phonon thermostat allows direct access to the polaron lifetimes.
