  • The authors report on the implementation of a photonic crystal waveguide with hyperbolic geometry supporting bound-in-the continuum exciton-polariton condensates. This unveils the coexistence of evanescent and ballistic polariton coupling behaviour with all-optical control.

  • Experimental evidence is presented for a new implementation of supersolidity in a driven-dissipative, non-equilibrium context realized in a photonic-crystal waveguide, demonstrating the breaking of translational symmetry with exceptionally low losses.

  • Bound states in the continuum are topological states with useful symmetry protection properties. An experiment now shows how to use them to form macroscopically coherent complexes of polariton condensates.

  • Superfluid flow around a vortex is quantized so that vortices become discrete, particle-like defects, with interactions mediated by the surrounding fluid. Here, the authors use a polariton system to experimentally investigate the behavior and scattering of vortices in a two-component superfluid.

  • Engineering the energy dispersion of polaritons in microcavities can yield intriguing effects such as the anomalous quantum Hall and Rashba effects. Now, different Berry curvature distributions of polariton bands are obtained in a strongly coupled organic–inorganic two-dimensional perovskite single-crystal microcavity and can be modified via temperature and magnetic field variation.
