    Sublattice symmetry has long been synonymous with chiral symmetry when it comes to topological classification. Here, the authors challenge this notion by systematically investigating sublattice symmetry and revealing its spatial nature with a precise description in terms of symmetry algebra and representation.

    Synthetic optical materials have been recently employed as a powerful platform for the emulation of topological phenomena in wave physics. Topological phases offer exciting opportunities, not only for fundamental physics demonstrations, but also for practical technologies. Yet, their impact has so far been primarily limited to their claimed enhanced robustness. Here, we clarify the role of robustness in topological photonic systems, and we discuss how topological photonics may offer a wider range of important opportunities in science and for practical technologies, discussing emergent and exciting research directions.
