  • This work creates a magnon-photon interface from a 2D magnetic semiconductor metasurface. It demonstrates both the static and ultrafast control of exciton polaritons with spins and coherent magnons, paving the way for spin-based photonic devices.

  • Exciton-polaritons result from the strong coupling of excitons and photons, exhibiting strong nonlinearity. Here, Zhao et al demonstrate room-temperature optical polariton spin-switching in a tungsten disulfide superlattice.

  • The authors embed a multiple quantum-well WS2 heterostructure in a planar microcavity and show the systematic control of the normal mode coupling-strength. They find a strong enhancement of the characteristic time scale, which they attribute to long-lived dark excitations emerging in the structure.

  • Superfluidity is a phenomenon usually restricted to cryogenic temperatures, but organic microcavities provide the conditions for a superfluid flow of polaritons at room temperature.

  • Evidence is provided for the formation of a collective state of short-lived excitons whose propagation resembles that of a classical liquid flows, with a speed reaching ~6% the speed of light.

  • 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.
