Resonant scattering in the topological Dirac semimetal Cd3As2Vladimir Gnezdilov1,2, Azat Sharafeev1, •Peter Lemmens1, Raman Sankar3, and Fangcheng Chou31IPKM, TU-BS, Braunschweig — 2ILTPE NAS, Ukraine — 3CCMS, National Taiwan Univ., Taipei, Taiwan

In the symmetry-broken topological Dirac semimetal with strong spin-orbit coupling, Cd3As2, a pronounced temperature evolution of quasielastic electronic Raman scattering and resonant effects are observed. These effects are then compared to observations in topological insulators, as Bi2Se3.
