Thermic effects on the resonance fluorescence of doubly dressed artificial atoms

In this work, operation robustness of controlled density of optical states under phonon dissipation is studied for an artificial atom simultaneously driven by two distinguishable fields. We investigate the influence of carrier-phonon interaction on the emission properties of the doubly driven two-level system by using both, perturbative and polaron approaches. Phonon effects are evidenced through comparing emission spectra obtained for finite temperatures, with that calculated at zero temperatures where lattice vibrations are absent.
