Light propagation through ensembles of nuclear two-level systems — •Deniz Adigüzel, Miriam Gerharz, and Jörg Evers — Max-Planck-Institut für Kernphysik, Heidelberg, Germany

Recent experiments at X-ray free electron lasers allow one to access new excitation regimes. The light-matter interactions can be studied by solving the optical-Bloch equations. Observing an ensemble of atoms, the light is scattered off of these atoms either coherently or incoherently. By comparing the intensities of these quantities, one can show that in the low-excitation regime their ratio remains constant in time[1]. However, [1] focused on settings in which propagation effects could be neglected. Here we study the light propagation through an ensemble of atoms beyond the low excitation regime in situations in which propagation effects are of relevance and compare the coherent/incoherent radiation.
