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…
