  text: We study the influence of the phonon environment on the electron dynamics
    in a doped quantum dot molecule. A non-perturbative quantumkinetic theory based
    on correlation expansion is used in order to describe both diagonal and off-diagonal
    electron-phonon couplings representing real and virtual processes with relevant
    acoustic phonons. We show that the relaxation is dominated by phononassisted electron
    tunneling between constituent quantum dots and occurs on a picosecond time scale.
    The dependence of the time evolution of the quantum dot occupation probabilities
    on the energy mismatch between the quantum dots is studied in detail.
