  In the present paper, we propose that the chiral magnetic effect, the direct
consequence of the presence of Weyl points in the band structure, can be
detected by its coupling to certain phonon modes, which behave like pseudo
scalars under point group transformations. Such coupling can generate resonance
between intrinsic plasmon oscillation and the corresponding phonon modes,
leading to dramatic modification of the optical response by the external
magnetic field, which provides a new way to study chiral magnetic effect by
optical measurements.
