Abstract

We investigate the far infrared magneto-optical transitions in
self-assembled InAs quantum dots with different. lateral
diameters and we show that a purely electronic model is unable
to account for the experimental data. We calculate them
coupling between the mixed electron-LO-phonon states using the,
Frohlich Hamiltonian, from which we determine the polaron
states as well as the energies of the dipolar electric
transitions. The excellent agreement between the experiments
and the calculations obtained for the different samples
provides strong evidence that the magneto-optical transitions
arise between polaron states and that the electrons and LO
phonons experience a strong coupling regime.
