Query: Transmission/reflection coefficients and Faraday/Kerr rotations as a
  function of applied magnetic fields in spin-orbit coupled Dirac metals   We reveal the nature of propagation and reflection of light in Weyl metals
with broken time reversal symmetry, whose electromagnetic properties are
described by axion electrodynamics. These Weyl metals turn out to play the role
of a chiral prism: An incident monochromatic wave can split into three waves
propagating with different wave numbers, depending on its chirality and
polarization (right $\&$ left circular polarizations and linear polarization
along the propagating direction). The helicity of the propagating/reflected
light is determined by $\textbf{B}_{ext}$ and $\textbf{E}_{light}$, where
$\textbf{B}_{ext}$ is the gradient of the $\theta-$field in the axion term
given by the applied magnetic field and $\textbf{E}_{light}$ is the
electric-field component of the incident light. This implies that the direction
of the external magnetic field controls the Faraday/Kerr rotation. In
particular, we find that the linear polarization of the oscillating electric
field along the propagating direction, which cannot occur in conventional
metals, arises when Weyl nodes are aligned along the oscillating magnetic
field. We evaluate both transmission/reflection coefficients and Faraday/Kerr
rotation angles as a function of both an external magnetic field and frequency
for various configurations of light propagation. We propose their strong
magnetic-field dependencies as one of the fingerprints of the axion
electrodynamics.
