Brief Project Outline
Quantum optics and condensed-matter are traditionally two separate branches of physics. The former being concerned with the interactions between atoms and photons, the latter with the effects of multi-particle systems in which local and non-local effects are observed. Recently, these two fields have started to overlap, resulting in such concepts as circuit-QED and quantum optics experiments in solid-state systems. We are interested in how quantum optics concepts can be implemented in solid-state systems as well as how condensed-matter effects can be observed in interacting atom-photon systems. Recent work includes:
- The study of "solid-light", the prediction of Mott-Insulator type transitions in systems of coupled photonic cavities and strongly coupled atoms.
- The propagation of excitations in nonlinear photonic cavity systems and their use in simulating classical and quantum optical elements.
- The interaction of coherent and incoherent processes within a Jaynes-Cummings lattice system and the resulting correlated emission.
