WG4 Cooperative effects, correlations and many-body physics tailored by strongly confined optical fields.
Explore quantum regimes of light-matter interaction such as super radiance in nanostructured solid-state systems and surface plasmon lasing.
Study polaritonic effects in nanostructures to attain quantum correlations between light and matter even in the presence of fast dephasing processes.
Investigate transmitted photon quantum entanglement through nanostructured media, e.g. metallic hole arrays with a photon-plasmon-photon conversion process. A remarkable effect, which may have considerable applications in quantum-imaging technologies.
Develop light induced self-organization of atoms in strongly confined light fields as nano-fibres and microresonators. Here single particles significantly act back on the light field, providing a new and efficient source of optical nonlinearity at the few photon – few atom level.
