Topological Optics Viewing topology in higher dimensionsIan S. OsborneArtistic depiction of a four-dimensional regular lattice that forms a quasicrystalline pattern with fivefold symmetry when projected in two dimensions. The symmetry and topology of physical systems are closely related to the symmetries governing the topological properties. Quasicrystals are ordered systems but have no translation or rotational symmetries.
