Adeleke, and Yansun Yao SrMnSb 2 is a candidate Dirac semimetal whose electrons near the Y point have the linear dispersion and low mass of a Dirac cone. Here we demonstrate that ultrafast, 800-nm optical pulses can launch coherent phonon oscillations in Sr 0.94 Mn 0.92 Sb 2 , particularly an A g mode at 4.4 THz. Through first-pri... [Phys. Rev.
