Web1 day ago · Higher-order topological phases host anomalous gapless boundary states (e.g., corner states and hinges states) which go beyond the celebrated bulk-boundary correspondence, a guiding principle in topological matter. Higher-order topology had been identified in both bulk gapped and gapless systems yet restricted to crystal structures. In … WebMay 24, 2024 · Here, we realize the higher-order topological states in a two-dimensional (2D) continuous elastic system. We experimentally observe the gapped one-dimensional (1D) edge states, the trivially...
WebIn a cube-shaped, strong topological insulator, for example, all six faces can conduct electrons robustly. In a weak TI, only four sides are conducting, while the top and bottom surfaces remain insulating. In a higher-order TI, electrons move only along selected hinges, where two crystal faces intersect. WebPhotonic topological states have revolutionized the understanding of the propagation and scattering of light. The recent discovery of higher-order photonic topological insulators opens an emergent horizon for 0D topological corner states.
