Topological n-root Su–Schrieffer–Heeger model in a non-Hermitian photonic ring system
Square-root topology is one of the newest additions to the ever expanding field of topological insulators (TIs). It characterizes systems that relate to their parent TI through the squaring of their Hamiltonians. Extensions to 2n-root topology, where n is the number of squaring operations involved i...
