This article reviews recent theoretical and experimental advances in the fundamental
understanding and active control of quantum fluids of light in nonlinear optical systems. In …

The Dicke model describes the coupling between a quantized cavity field and a large
ensemble of two‐level atoms. When the number of atoms tends to infinity, this model can …

We study a disordered ensemble of quantum emitters collectively coupled to a lossless
cavity mode. The latter is found to modify the localization properties of the “dark” eigenstates …

Exciton–polaritons in a microcavity are composite two-dimensional bosonic quasiparticles,
arising from the strong coupling between confined light modes in a resonant planar optical …

Large arrowhead matrices with randomly distributed entries describe a variety of important
phenomena where a degree of freedom is nonlocally coupled to a disordered continuum of …

Large exciton-polariton optical nonlinearities present a key mechanism for photonics-based
communication, ultimately in the quantum regime. Enhanced nonlinear response from …

We derive the equation of motion for a Bose-Einstein condensate of photons in a dye-
microcavity system, starting from Maxwell's equations. Our theory takes into account mirror …

We develop a quantum model for nonequilibrium Bose-Einstein condensation of photons
and polaritons in planar microcavity devices. The model builds on laser theory and includes …

Bogoliubov's theory states that self-interaction effects in Bose-Einstein condensates produce
a characteristic linear dispersion at low momenta. One of the curious features of …

A theoretical model is presented which explains the dominant decoherence process in a
microcavity polariton condensate. The mechanism which is invoked is the effect of self …
