THz magneto-optical study of Weyl semimetal TaAs

ORAL

Abstract

Weyl semimetals are predicted to exhibit novel magneto-optical-like effects due to Berry phase singularities associated with the Weyl nodes. It was predicted theoretically and confirmed by ARPES experiments that TaAs is a low doped Weyl semimetal with the broken spatial inversion symmetry. We will report on the results of our experimental broad band THz reflectivity magneto-optical study of TaAs single crystals in Faraday and Voigt geometries.
