Radiative and phonon-induced dephasing in double quantum dots
arXiv:0908.1487 · doi:10.1088/1742-6596/193/1/012136
Abstract
A simple method for describing the evolution of a quantum state of a double quantum dot system interacting simultaneously with the electromagnetic environment and with the lattice modes is developed. It is shown that the joint action of the two reservoirs leads to nontrivial effects in the system dephasing. As an example, the impact of phonon-induced initial dephasing on the radiative decay of delocalized exciton states is discussed.
