A semiconductor microcavity polariton fluid, injected by a nearly-resonant continuous wave
pump laser, can exhibit collective excitations which deeply modify its propagation. When the
polariton density is high enough, a superfluid behaviour of the polariton fluid is observed
and manifests itself as the suppression of scattering from defects. In other conditions
Cerenkov-like patterns are observed. These new effects can be compared to the ones
observed in ultra-cold atomic ensembles. Microcavities polaritons are thus very good tools
for exploring the physics of non-equilibrium quantum fluids.
