Terahertz Generation Measurements in Inversion-Symmetry Breaking Weyl Semimetals with Spectrally Resolved Excitation Fields

ORAL

Abstract

Topological materials, and in particular Weyl semimetals, offer a playground for diverse optical properties. When inversion symmetry is broken, such materials additionally allow second-order bulk nonlinear effects. We present terahertz generation data with excitation fields ranging across the near infrared spectrum. Measurements were taken with both linear- and circular-polarized light in a variety of geometries.
