Abstract : We first discuss how topological physics can be observed for photons; specifically, how various quantum Hall models can be simulated in an optical system. We report on the imaging and measurement of topological photonic edge states and the generation of correlated-photon pairs, in silicon photonics platform. We then discuss how strong interaction between photons can be created by the integration of topological photonic structures with solid-state quantum emitters.
Moreover, we describe how photons, in a different role, could be exploited to probe and manipulate electronic states. Examples include: (1) optical creation and manipulation of topological excitations with light, (2) light-induced superconductivity and topology. More generally, we discuss how quantum optics toolbox can be used to probe and manipulate correlated states of electrons.
