Optical evidence of the chiral magnetic anomaly in the Weyl semimetal TaAs

Chiral pumping from optical electric fields oscillating at terahertz frequencies is observed in the Weyl material TaAs with electric and magnetic fields aligned along both the and axes. Free-carrier spectral weight enhancement is measured directly, confirming theoretical expectations of chiral pumpi...
