The coherent exchange of energy between materials and optical fields leads to strong light–
matter interactions and so-called polaritonic states with intriguing properties, halfway …

Abstract The study of Bose–Einstein condensation effects in photonic systems has revealed
a rich phenomenology related to spontaneous coherence generation in driven-dissipative …

Exciton polaritons are quasiparticles of photons coupled strongly to bound electron-hole
pairs, manifesting as an anti-crossing light dispersion near an exciton resonance. Highly …

Recently a new type of system exhibiting spontaneous coherence has emerged—the
exciton–polariton condensate. Exciton–polaritons (or polaritons for short) are bosonic …

Bound states in the continuum (BICs),–are peculiar topological states that, when realized in
a planar photonic crystal lattice, are symmetry-protected from radiating in the far field despite …

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 …
