Richard, and Jimin Zhao We report an ultrafast lattice dynamics investigation of the topological Dirac semimetal C d 3 A s 2 . A coherent phonon beating among three evenly spaced A 1 g optical phonon modes (of frequencies 1.80, 1.96, and 2.11 THz, respectively) is unambiguously observed. The two side modes originate from the count… [Phys. Rev. B 95, 235108] Published Mon Jun 05, 2017
