DESCRIPTION:Prof. Elisabeth Giacobino\,  Laboratoire Kastler Brossel\, Eco
 le Normale Supérieure\, France\nA semiconductor microcavity polariton flu
 id\, injected by a nearly-resonant continuous wave \npump laser\, can exhi
 bit collective excitations which deeply modify its propagation. When the \
 npolariton density is high enough\, a superfluid behaviour of the polarito
 n fluid is observed \nand manifests itself as the suppression of scatterin
 g from defects. In other conditions \nCerenkov-like patterns are observed.
  These new effects can be compared to the ones \nobserved in ultra-cold at
 omic ensembles. Microcavities polaritons are thus very good tools \nfor ex
 ploring the physics of non-equilibrium quantum fluids.
