Findings

Conductivity and thermal conductivity show strong anisotropic magnetic field dependence.

Existence of magneto-plasmons and magneto-polaritons determined by the chiral anomaly.

Conditions for the quasi-classical description of electron transport are discussed.

Abstract

We present a theory of magnetotransport phenomena related to the chiral anomaly in Weyl semimetals. We show that conductivity, thermal conductivity, thermoelectric and the sound absorption coefficients exhibit strong and anisotropic magnetic field dependences. We also discuss properties of magneto-plasmons and magneto-polaritons, whose existence is entirely determined by the chiral anomaly. Finally, we discuss the conditions of applicability of the quasi-classical description of electron transport phenomena related to the chiral anomaly.
