Abstract 2D and 3D solitons and related states, such as quantum droplets, can appear in
optical systems, atomic Bose–Einstein condensates (BECs) and liquid crystals, among other …

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 …

Semiconductor excitations can hybridize with cavity photons to form exciton-polaritons (EPs)
with remarkable properties, including light-like energy flow combined with matter-like …

Superfluidity—the suppression of scattering in a quantum fluid at velocities below a critical
value—is one of the most striking manifestations of the collective behaviour typical of Bose …

Quantum fluids exhibit quantum mechanical effects at the macroscopic level, which contrast
strongly with classical fluids. Gain-dissipative solid-state exciton-polaritons systems are …

Artificial gauge fields are currently realized in a wide range of physical settings. This
includes solid-state devices but also engineered systems, such as photonic crystals …

The experimental realization of Bose-Einstein condensation (BEC) with atoms and
quasiparticles has triggered wide exploration of macroscopic quantum effects. Microcavity …

The nonlinear propagation of coherent optical fields has been extensively explored in the
framework of nonlinear optics, while the linear propagation of incoherent fields has been …

Turbulent phenomena are among the most striking effects that both classical and quantum
fluids can exhibit. Although classical turbulence is ubiquitous in nature, the observation of …

The phenomenon of Bose–Einstein condensation is a phase transition originally predicted
by Bose and Einstein in 1924. In particular, it was shown that below a critical temperature T …
