Abstract
We analyzed time evolution of the localized charge in the
system of two interacting single level quantum dots (QDs) coupled
with the continuous spectrum states in the presence of
electron-phonon interaction.
We demonstrated that electron-phonon interaction leads to the
increasing of localized charge relaxation rate. We also found that
several time scales with different relaxation rates appear in the
system in the case of non-resonant tunneling between the dots. We
revealed the formation of oscillations in the filling numbers time
evolution caused by the emission and adsorption processes of
phonons.
