Abstract = {{Superfluidity, which is the ability of a liquid or gas to flow with zero
   viscosity, is one of the most remarkable implications of collective
   quantum coherence. In equilibrium systems such as liquid He-4 and
   ultracold atomic gases, superfluid behavior conjugates diverse yet
   related phenomena, such as a persistent metastable flow in multiply
   connected geometries and the existence of a critical velocity for
   frictionless flow when hitting a static defect. The link between these
   different aspects of superfluid behavior is far less clear in
   driven-dissipative systems displaying collective coherence, such as
   microcavity polaritons, which raises important questions about their
   concurrency. With a joint theoretical and experimental study, we show
   that the scenario is particularly rich for polaritons driven in a
   three-fluid collective coherent regime, i.e., a so-called optical
   parametric oscillator. On the one hand, the spontaneous macroscopic
   coherence following the phase locking of the signal and idler fluids has
   been shown to be responsible for their simultaneous quantized flow
   metastability. On the other hand, we show here that the pump, signal,
   and idler have distinct responses when hitting a static defect; while
   the signal displays modulations that are barely perceptible, the ones
   appearing in the pump and idler are determined by their mutual coupling
   due to nonlinear and parametric processes.}},
