High-frequency transverse phonons in amorphous materials observed for the first time

Description

Recently, with the state-of-the-art neutron scattering instrumentation and molecular dynamic simulations, an international research team, led by physicists from City University of Hong Kong (CityU), has demonstrated the existence of high-frequency transverse phonons in metallic glass for the first time. Their findings also suggest that the atomic structure correlates with its atomic dynamics, providing new insight for understanding the atomic structure-dynamics relationship in disordered materials.
