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 …

Ultrafast all-optical switches and integrated circuits call for giant optical nonlinearity to
minimize energy consumption and footprint. Exciton polaritons underpin intrinsic strong …

We determine the steady-state phases of a driven-dissipative Bose-Hubbard model,
describing, eg, an array of coherently pumped nonlinear cavities with a finite photon lifetime …

Manipulation of nonlinear waves in artificial periodic structures leads to spectacular spatial
features, such as generation of gap solitons or onset of the Mott insulator phase transition …

The dynamics of propagating polariton condensates in one-dimensional microcavities is
investigated through time resolved experiments. We find a strong increase in the …

Although organic polariton condensation has been recently demonstrated, they only utilize
the photon part of polaritons and ignore the excitonic contribution because the polariton …

We theoretically study Hawking radiation processes from an analog acoustic black hole in a
flowing superfluid of exciton-polaritons in a one-dimensional semiconductor microcavity …

We present analytical solutions for the mean-field master equation of the driven-dissipative
Bose-Hubbard model for cavity photons, in the limit of both weak pumping and weak …

We report the observation of strong coupling between quantum well excitons and a guided
mode of a semiconductor planar waveguide by observation of anticrossing in the dispersion …

Exciton-polaritons, hybrid light-matter excitations arising from the strong coupling between
excitons in semiconductors and photons in photonic nanostructures, are crucial for exploring …
