Momentum-Resolved Direct Observation of Chiral Phonons in Elemental Tellurium
Author(s): Qiyang Sun, Songrui Hou, Ayman H. Said, Yanzhong Pei, Jie Ma, Wei Tian, and Chen Li
Chiral phonons carry finite phonon angular momentum, yet their momentum-resolved behavior in acoustic branches remains largely unexplored. Here, we report the direct detection of chiral acoustic phonons in elemental Te. Through a combination of high-energy-resolution inelastic x-ray scattering exper… [Phys. Rev.
