In this project you will couple tunable optical microcavities with nanostructured excitonic materials to achieve strong photon-photon interactions. You will use these interactions to investigate phase transitions of light, and to evidence the conditions under which noise can enhance the transport of excitations in complex systems. By designing cavity arrays with different dimensionalities and geometries, you will tailor the potential landscape in which photons hop and interact. This will allow you to emulate the behaviour of condensed matter systems with light.
