Condensed Matter Physics Seminar
“Chiral Photocurrents and Terahertz Emission in Dirac/Weyl Semimetals”
Evan Philip
Department of Physics & Astronomy

I will start with an introduction to Dirac/Weyl semimetals and chiral anomaly. We will then look at a new mechanism for photocurrents in Dirac/Weyl semimetals that relies on the chiral anomaly. I will also discuss terahertz emission from the Weyl semimetal TaAs induced by a near-infrared laser, where Weyl fermions play a central role. We will conclude with remarks on some potential applications of these works.
