Photon transport in one–dimensional systems coupled to three–level quantum impurities — •Christoph Martens1, Paolo Longo1, and Kurt Busch2,3 — 1Institut für Theoretische Festkörperphysik and DFG–Center for Functional Nanostructures (CFN), Karlsruhe Institute of Technology (KIT), 76128 Karlsruhe, Germany — 2Humboldt Universität zu Berlin, Institut für Physik, AG Theoretische Optik, Newtonstr. 15, 12489 Berlin, Germany — 3Max-Born-Institut, Max-Born-Str. 2A, 12489 Berlin, Germany
Recent studies on the dynamics of photon transport in waveguiding systems in the presence of a quantum impurity show interesting transport properties [1-4], for instance, strong effective photon–photon interactions [1,4], interaction–induced radiation trapping [2] and electromagnetically induced transparency [3,4]. In this contribution, we present our recent results on such systems with the quantum impurity modeled as a single undriven or driven three–level system. By monitoring the time evolution of few–photon pulses we investigate the transmission characteristics in position and momentum space. Furthermore, we analyze the conditions under which long time occupation of the excited states of the three–level system or even the excitation of an atom–photon bound state can occur.
