Few-photon transport in low-dimensional waveguides with a quantum-impurity — •Christoph Martens, Jean-Christophe Blancon, Paolo Longo, and Kurt Busch — Institut für Theoretische Festkörperphysik and DFG-Center for Functional Nanostructures (CFN), Karlsruhe Institute of Technology (KIT), 76128 Karlsruhe, Germany

We present our recent results on the dynamics of few-photon quantum transport in waveguiding systems in the presence of a quantum impurity. Based on a multimode Jaynes-Cummings model, recent studies show interesting transport properties [1,2,3,4], for instance, effective photon-photon interactions [1,3] and interaction-induced radiation trapping [3]. By monitoring the time evolution of few-photon pulses we investigate the transmission characteristics and the conditions under which atom-photon bound states can be excited. Furthermore, we analyze functional elements which are important for possible experimental realizations.
