|Abstract:||Acoustic phonons have recently been posited as playing an integral role in explaining the half-quantized thermal Hall effect in α-RuCl3. Therefore, we present much needed inelastic X-ray scattering measurements of its acoustic phonon dispersion, along with calculations using the frozen-phonon method. We also discuss a temperature study which conclusively shows a first-order structural transition to a non-C2/m space group at low temperature. Together these results are an important backbone for future theoretical and experimental studies of α-RuCl3. © 2022 American Physical Society.|
