Transverse Peierls Transition

We propose a new type of spontaneous symmetry breaking phase caused by softening the transverse acoustic phonon modes through electron-phonon coupling. These phases include shear density wave and self-twisting wave, which are linearly circularly polarized modes, respectively. that two topological semimetal systems in quantum limit, where electrons only occupy lowest Landau bands under external magnetic field, will be perfect to realize these phases. Exotic physical effects induced phases, including 3D Hall effect, chiral standing magnetoacoustic effects, correction Einstein–de Hass effect.1 MoreReceived 20 April 2022Revised 13 October 2022Accepted 23 January 2023DOI:https://doi.org/10.1103/PhysRevX.13.011027Published American Physical Society terms Creative Commons Attribution 4.0 International license.
