Query: Dynamic chiral magnetic effect and anisotropic natural optical activity
  of tilted Weyl semimetals   We study the dynamic chiral magnetic conductivity (DCMC) and natural optical
activity in an inversion-broken tilted Weyl semimetal (WSM). Starting from the
Kubo formula, we derive the analytical expressions for the DCMC for two
different directions of the incident electromagnetic wave. We show that the
angle of rotation of the plane of polarization of the transmitted wave exhibits
remarkable anisotropic behavior and is larger along the tilt direction. This
striking anisotropy of DCMC which results in anisotropic optical activity and
rotary power, can be experimentally observed as a topological magneto-electric
effect of inversion-broken tilted WSMs. Finally, using the low energy
Hamiltonian, we show that the DCMC follows the universal $\frac{1}{\omega^2}$
decay in the high frequency regime. In the low frequency regime, however, the
DCMC shows sharp peaks at the tilt dependent effective chemical potentials of
the left-handed and right-handed Weyl points. This can serve as a signature to
distinguish between the type-I and type-II Weyl semimetals.
