In this issue, the article Validity of the quantum regression theorem for resonance fluorescence in a photonic crystal by G. Boedecker and C. Henkel (pp. 805–813) analyzes the correlation functions of a driven two-level system embedded in a photonic crystal. The image shows linear absorption spectra for different laser frequencies and is a modified version of Figure 2 in this article.
