Chiral kinetic theory and anomalous hydrodynamics in even spacetime dimensions

Abstract

We apply chiral kinetic theory to a gas of weakly interacting Weyl fermions coupled to electromagnetism in (2N  +  1)  +  1 spacetime dimensions to obtain the ‘Gibbs free energy current’ from which all equilibrium finite temperature anomalous contributions, such as the chiral magnetic and vortical currents, can be derived. Our results agree with those derived previously using thermodynamic constraints.
