"Three dimensional topological semimetal Cd3As2: insights from magneto-optical spectroscopy"

Presented by Ana Akrap, University of Geneva, Switzerland

Wednesday, October 21, 2015, 1:30 pm — Bldg. 480 Conf. Room

Cd3As2 is a three-dimensional Dirac semimetal, with two Dirac cones around the Gamma point shifted away from each other along the (001) direction. It is known that the Dirac cones appear due to band inversion, although their exact scale is not clear at the moment. I will talk about zero-field optical conductivity, and high-field magneto-reflectivity of this material, and address some of the open questions regarding the band structure.
