Polaritons are hybrid light-matter quasiparticles that condense into a quantum fluid at sufficiently high densities. Although two-dimensionnal hybrid lead-halide perovskites seem to be the ideal material platform to observe polaritons condensation, reports of quantum fluidics in these systems remain scarce. Here, using coherent non-linear spectroscopy, we provide insights into the mechanisms behind this reluctance to condensation. These insights provide guidance to the design of photonic systems to steadily achieve polariton condensation using these promising materials.
