Chiral Anomaly and Classical Negative Magnetoresistance of Weyl Metals

Understand

We consider the classical magnetoresistance of a Weyl metal in which the electron Fermi surface possess nonzero fluxes of the Berry curvature.

• Such a system may exhibit large negative magnetoresistance with unusual anisotropy as a function of the angle between the electric and magnetic fields.
• In this case the system can support a new type of plasma waves.
• These phenomena are consequences of chiral anomaly in electron transport theory.
