    • Actively controllable topological phase transition in phononic beam systems 

      Zhou, Weijian; Chen, Weiqiu; Destrade, Michel; Lim, C.W. (Elsevier, 2020-05-01)
      Topological insulators, which allow edge or interface waves but forbid bulk waves, have revolutionized our scientific cognition of acoustic/elastic systems. Due to their nontrivial topological characteristics, edge (interface) ...
