Observation of the Adler-Bell-Jackiw chiral anomaly in a Weyl semimetal

TL;DR

This paper reports the experimental observation of the Adler-Bell-Jackiw chiral anomaly in a Weyl semimetal, providing direct evidence of this quantum phenomenon in a solid-state system.

Contribution

First experimental demonstration of the Adler-Bell-Jackiw chiral anomaly in a Weyl semimetal crystal.

Findings

Observation of negative magnetoresistance consistent with chiral anomaly

Confirmation of Weyl fermions in the material

Evidence supporting theoretical predictions of chiral anomaly effects

Abstract
