Thermal and gravitational chiral anomaly induced magneto-transport in Weyl semimetals

Abstract

This paper demonstrates three anomalies: namely thermal, gravitational, and electrical chiral anomalies in Weyl semimetals, within a semiclassical framework. Amongst these, the thermal chiral anomaly, which causes chiral charge and chiral energy imbalance in a Weyl semimetal in presence of a temperature gradient parallel to the magnetic field, is novel and has not been explored earlier. In addition, the authors also explore the impact of these on magneto-thermal transport experiments in Weyl semimetals.
