Topological Phase Transition in a One-Dimensional Elastic String System

Topological Phase Transition in a One-Dimensional Elastic String System

We show that topological interface mode can emerge in a one-dimensional elastic string system which consists of two periodic strings with different band topologies. To verify their topological features, Zak-phase of each band is calculated and reveals the condition of topological phase transition ac...
