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

Understand

Quantum anomalies in Weyl semimetal (for either ${\bf E}\cdot{\bf B} \neq 0$ or ${\bf \nabla}T\cdot{\bf B} \neq 0$) leads to chiral charge and energy pumping between the opposite chirality nodes.

• This results in chiral charge and energy imbalance between the Weyl nodes which manifests in several intriguing magneto-transport phenomena.
• Here, we investigate the role of electrical-, thermal-, and gravitational chiral anomaly on magneto-transport in Weyl semimetals.
• We predict the planar Ettinghausen and Righi-Leduc effect to be a distinct signature of these quantum anomalies.
