  • Smooth topological photonic interfaces lead to less localized boundary modes which improves their guiding characteristics in both spin- and valley Hall metasurfaces. The modes become insensitive to the lattice details, showcasing improved bandgap crossing and longer propagation distances.

  • Using pump-power-dependent exciton absorption spectroscopy, the authors reveal magnon-mediated exciton–exciton interactions and a consequent nonlinear optical response in CrSBr, an antiferromagnetic semiconductor.

  • Topological traps and guides for polaritons expand the potential for light-matter wave manipulation in ultrathin materials, facilitating photonic on-chip integration. Here the authors demonstrate a chiral-defect cavity in a planar metasurface that efficiently trap mid-IR phonon-polaritons in topological defects.
