Thermoelectric signature of the chiral anomaly in Cd3As2
The thermoelectric effect can be used to explore electronic properties. Here, the authors show experimentally that Cd3As2exhibits a negative magnetic thermopower which reverses sign at high field, and relate it to the chiral anomaly, a signature of Weyl fermions.
