Magnetoelastic hybrid excitations in CeAuAl 3 [PDF]
Proceedings of the National Academy of Sciences, 2019 Nearly a century of research has established the Born–Oppenheimer approximation as a cornerstone of condensed-matter systems, stating that the motion of the atomic nuclei and electrons may be treated separately. Interactions beyond the Born–Oppenheimer approximation are at the heart of magneto-elastic functionalities and instabilities.
