Chirality-Induced Phonon Dispersion in a Noncentrosymmetric Micropolar Crystal

Features of the phonon spectrum of a chiral crystal are examined within the micropolar elasticity theory. This formalism accounts for not only translational micromotions of a medium but also rotational ones. It is found that there appears the phonon band splitting depending on the left- and right-ci...
