Electronic Origin of Non-Zone-Center Phonon Condensations: Octahedral Rotations as A Case Study

Suguru Yoshida, Hirofumi Akamatsu, Katsuro Hayashi

Unstable zone-boundary phonon modes drive atomic displacements linked to a rich array of properties. Yet, the electronic origin of the instability remains to be clearly explained.…
