Photon path representation for multiphoton states — •Nils Griebe and Gernot Alber — Institut für Angewandte Physik, Technische Universität Darmstadt, 64289

We develop a method for calculating the time evolution of several initially excited two level atoms inside a cavity or in free space. Our method is a generalization of the known photonic path representation for only one initial excitation and as such well suited for dealing with multimode scenarios. Similar to the case of only one initial excitation our method generates a series of terms. In an approach similar to the Feynman diagrams each of these terms can be uniquely connected to a descriptive diagram. These diagrams correspond to photon paths which contain spontaneous decay, absorption and stimulated emission processes.
