Query: Nonreciprocal optics and magnetotransport in Weyl metals as signatures
  of band topology   We consider effects of spatial dispersion in noncentrosymmetric time-reversal
invariant Weyl metals in the presence of a static magnetic field. In
particular, we study currents that are linear in both the spatial derivatives
of an applied electric field, and the static magnetic field, which are
responsible for the phenomenon of gyrotropic birefringence. We show that the
chiral anomaly and the chiral magnetic effect make the leading contribution to
this class of phenomena in metals. We apply the obtained results to the problem
of electromagnetic wave transmission through a thin slab of a Weyl semimetal,
and show that the transmission coefficient contains a component that is odd in
the applied static magnetic field. As such, it can be easily distinguished from
conventional Ohmic magnetotransport effects, which are quadratic in the applied
magnetic field. The relative magnitude of the effect can reach a few percent in
Weyl materials subject to magnetic fields of 0.1Tesla, while the effect is
several orders of magnitude smaller in metals without Berry monopoles. We
conclude that the nonreciprocal optical and magnetotransport effects can be a
robust probe of band topology in metals.
