Topological defect states in elastic phononic plates
Baizhan Xia, Liang Tong, Jie Zhang +2
Topological defects (including disclinations and dislocations) which commonly exist in various materials have shown an amazing ability to produce excellent mechanical and physical…
Three-dimensional higher-order topological acoustic system with multidimensional topological states
Baizhan Xia, Shengjie Zheng, Liang Tong +3
Topologically protected gapless edge/surface states are phases of quantum matter which behave as massless Dirac fermions, immunizing against disorders and continuous perturbations.…
Pseudospin-valley-coupled phononic topological insulator with edge and corner states
Haiyan Fan, Baizhan Xia, Shengjie Zheng +1
Topologically protected gapless edge states are phases of quantum matter which behave as massless Dirac fermions, immunizing against disorders and continuous perturbations. Recentl…
Elastic higher-order topological insulator with topologically protected corner states
Haiyan Fan, Baizhan Xia, Liang Tong +2
Topologically gapless edge states, characterized by topological invariants and Berry's phases of bulk energy bands, provide amazing techniques to robustly control the reflectionles…
