Query: Electric manipulation of domain walls in magnetic Weyl semimetals via
  the axial anomaly   We show how the axial (chiral) anomaly induces a spin torque on the
magnetization in magnetic Weyl semimetals. The anomaly produces an imbalance in
left- and right-handed chirality carriers when non-orthogonal electric and
magnetic fields are applied. Such imbalance generates a spin density which
exerts a torque on the magnetization, the strength of which can be controlled
by the intensity of the applied electric field. We show how this results in an
electric control of the chirality of domain walls, as well as in an improvement
of the domain wall dynamics, by delaying the onset of the Walker breakdown. The
measurement of the electric field mediated changes in the domain wall chirality
would constitute a direct proof of the axial anomaly. Additionally, we show how
quantum fluctuations of electronic Fermi arc states bound to the domain wall
naturally induce an effective magnetic anisotropy, allowing for high domain
wall velocities even if the intrinsic anisotropy of the magnetic Weyl semimetal
is small.
