Resonance fluorescence in a photonic crystal — •Geesche Boedecker and Carsten Henkel — Institut für Physik, Universität Potsdam, am Neuen Palais 10, 14469 Potsdam

One of the strong motivations for photonic crystals is the possibility of tuning the spontaneous decay rate of an embedded emitter. The strongly modified density of field modes makes the atom-field dynamics markedly non-Markovian, and this requires new techniques and approximations. In particular, the emission spectrum of a coherently driven two-state system into a photonic band structure has been characterized only in the weak coupling limit so far. We discuss numerically exact simulation schemes for this non-Markovian problem and compare them to approximations developed for the spin-boson model, starting from the Feynman-Vernon influence functional technique.
