Terahertz polarization conversion from optical dichroism in a topological Dirac semimetal
Topological Dirac semimetals (TDSMs), such as Cd 3 As 2 and Na 3 Bi, exhibit strong
optical dichroism with contrasting dielectric permittivity along different crystal axes. However …

Ellipticity control of terahertz high-harmonic generation in a Dirac semimetal
We report on terahertz high-harmonic generation in a Dirac semimetal as a function of the
driving-pulse ellipticity and on a theoretical study of the field-driven intraband kinetics of …
