Detecting the chiral magnetic effect by lattice dynamics in Weyl semimetals

Year: 2016

Type: article

Abstract: 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 pseudoscalars 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 way to study chiral magnetic effect by optical measurements.
