Chirality-induced Phonon Dispersion in a Noncentrosymmetric Micropolar Crystal
J. Kishine, A. S. Ovchinnikov, A. A. Tereshchenko
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 mediu…

Tensile deformations of the magnetic chiral soliton lattice probed by Lorentz transmission electron microscopy
G. W. Paterson, A. A. Tereshchenko, S. Nakayama +6
We consider the case of a chiral soliton lattice subjected to uniaxial elastic strain applied perpendicular to the chiral axis and derive through analytical modelling the phase dia…

Theory of magnetoelastic resonance in a mono-axial chiral helimagnet
A. A. Tereshchenko, A. S. Ovchinnikov, I. Proskurin +2
We study magnetoelastic resonance phenomena in a mono-axial chiral helimagnet belonging to hexagonal crystal class. By computing the spectrum of coupled elastic wave and spin wave,…
