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 …

In the past decade, a two-dimensional matter-light system called the microcavity exciton-
polariton has emerged as a new promising candidate of Bose-Einstein condensation (BEC) …

Exciton-polaritons in semiconductor microcavities have become a model system for the
studies of dynamical Bose–Einstein condensation, macroscopic coherence, many-body …

We develop a mean-field theory of the dynamics of a nonequilibrium Bose-Einstein
condensate of exciton polaritons in a semiconductor microcavity. The spectrum of …

We propose and characterize solid-state photonic structures where light experiences an
artificial gauge field. A nontrivial phase for photons tunneling between adjacent sites of a …

Coherent manipulation of spin ensembles is a key issue in the development of spintronics.
In particular, multivalued spin switching may lead to new schemes of logic gating and …

We report on the observation of spontaneous coherent oscillations in a microcavity polariton
bosonic Josephson junction. Condensation of exciton polaritons here takes place under …

We theoretically investigate the optical response of a one-dimensional array of strongly
nonlinear optical microcavities. When the optical nonlinearity is much larger than both …

We investigate the quantum nonlinear dynamics of a resonantly excited photonic quantum
dot embedding a quantum well in the strong exciton-photon coupling regime. Within a …

Optomechanical systems provide a pathway for the bidirectional optical-to-microwave
interconversion in (quantum) networks. These systems can be implemented using hybrid …
