  • Topological lasers with enhanced robustness have revolutionized the paradigm of laser design, yet their implementation in disclination geometries remains largely unexplored. Here, the authors demonstrate a mid-gap topological exciton-polariton laser in a C4v disclination perovskite lattice at room temperature.

  • Achieving propagating topological exciton polaritons at room temperature is challenging. Here, the authors demonstrate room-temperature valley-polarized topological polaritons with valley-dependent propagation in a perovskite lattice formed by two mutually inverted honeycomb lattices with a bearded interface.
