Terahertz Polarization Conversion from Optical Dichroism in a Topological Dirac Semimetal

Haiyu Meng, Lingling Wang, Ching Hua Lee +1

Topological Dirac semimetals (TDSM), such as Cd${}_3$As${}_2$ and Na${}_3$Bi, exhibits strong optical dichroism with contrasting dielectric permittivity along different crystal axes. How…
