Topological properties of coupled one-dimensional chains of elastic rotators

摘要: We introduce a model system composed of elastically coupled one-dimensional chains elastic rotators. The rotators are analogous to Su-Schrieffer–Heeger models. chain is shown analytically and numerically support an unusual number topological properties such as Dirac degeneracies, band inversion transition function the strength parameter coupling chains, nonseparability modes' degrees freedom along across that entangled Bell states in multipartite quantum system. Finally, we reveal formation synthetic dimension by allowing vary with time, which has potential create higher-dimensional space.
