Topological Edge States in Reconfigurable Multi-stable Mechanical Metamaterials
Zhen Wang, Feiyang Sun, Xiaodong Xu +3
Multi-stable mechanical structures find cutting-edge applications across various domains due to their reconfigurability, which offers innovative possibilities for engineering and t…
Elastic higher-order topological insulators with quantization of the quadrupole moments
Zhen Wang, Qi Wei, Heng-Yi Xu +1
We demonstrate that HOTIs with the quantization of the quadrupole moments can be realized in the two-dimensional elastic phononic crystals (PnCs). Both one-dimensional (1D) topolog…
Guiding Robust Valley-dependent Edge States by Surface Acoustic Waves
Zhen Wang, Fu-Kang Liu, Si-Yuan Yu +4
Recently, the concept of valley pseudospin, labeling quantum states of energy extrema in momentum space, has attracted enormous attention because of its potential as a new type of…
A Monolithic Topologically Protected Phononic Circuit
Si-Yuan Yu, Cheng He, Zhen Wang +6
Precise control of elastic waves in modes and coherences is of great use in reinforcing nowadays elastic energy harvesting/storage, nondestructive testing, wave-mater interaction,…
