@article{Tomadin2010ManybodyPI, title={Many-body phenomena in QED-cavity arrays [Invited]}, author={Andrea Tomadin and Rosario Fazio}, journal={Journal of The Optical Society of America B-optical Physics}, year={2010}, volume={27} }

Coupled quantum electrodynamics (QED) cavities have been recently proposed as new systems to simulate a variety of equilibrium and nonequilibrium many-body phenomena. We present a brief review of their main properties together with a survey of the latest developments of the field and some perspectives concerning their experimental realizations and possible new theoretical directions.
