Topological Node-Lines in Mechanical Metacrystals
Zhan Xiong, Hai-Xiao Wang, Jinjie Shi +4
Topological acoustic and elastic waves have recently emerged as an exciting interdisciplinary field which is still mainly focused on low-dimensional structures and model systems. H…
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,…
Zone folding induced topological insulators in phononic crystals
Yuanchen Deng, Hao Ge, Yuan Tian +2
This letter investigates a flow-free, pseudospin-based acoustic topological insulator. Zone folding, a strategy originated from photonic crystal, is used to form double Dirac cones…
3D nature of ZrTe band structure measured by high-momentum-resolution photoemission spectroscopy
H. Xiong, J. A. Sobota, S. -L. Yang +10
We have performed a systematic high-momentum-resolution photoemission study on ZrTe using eV photon energy. We have measured the band structure near the point, and quan…
