Magnetotransport in Dirac metals: chiral magnetic effect and quantum oscillations

Abstract

Dirac metals are characterized by the linear dispersion of fermionic quasi-particles, with the Dirac point hidden inside a Fermi surface. We study the magnetotransport in these materials using chiral kinetic theory to describe within the same framework both the negative magnetoresistance caused by chiral magnetic effect and quantum oscillations in the magnetoresistance due to the existence of the Fermi surface. We discuss the relevance of obtained results to recent measurements on $\mathrm{C}{\mathrm{d}}_3\mathrm{A}{\mathrm{s}}_2$.
