Validity of the quantum regression theorem for resonance fluorescence in a photonic crystal
Ann. Phys. (Berlin) 524 (2012) 805-13, highlight by Y. Lai, Ann. Phys. (Berlin) 524 (2012) A179 and picture on cover page.


    Correlation functions of a driven two-level system embedded in a photonic crystal are analyzed. The spectral density of the photonic bands near a gap makes this system non-Markovian. The equations of motion for two-time correlations are derived by two different methods, the quantum regression theorem and the fluctuation dissipation theorem, and found to be the same.
