Edge states and corner modes in second-order topological phononic crystal plates
Shao-yong Huo, Hong-bo Huang, Lu-yang Feng +1
We realize an elastic second-order topological insulator hosting both one-dimensional gapped edge states and zero-dimensional in-gap corner modes in the double-sided pillared phono…

Self-ordering induces multiple topological transitions for elastic waves in phononic crystals
Jiujiu Chen, Hongbo Huang, Shaoyong Huo +3
Topological defects with symmetry-breaking phase transitions have captured much attention. Vortex generated by topological defects exhibits exotic properties and its flow direction…
