Higher-order topology

Artistic image of light localized in a topological kagome photonic crystal composed of a carefully arranged array of dielectric pillars. Photons in the crystal are entangled due to topology and long-range interactions.

    Accessing the physics of higher-than-three-dimensional systems is naturally challenging. Researchers have now demonstrated that light dynamics in a one-dimensional array of carefully arranged photonic waveguides mimics the time evolution of particles in high-dimensional lattices.
