Frustration-induced diffusive scattering anomaly and dimension change in
Yaokun Su, Hillary L. Smith, Matthew B. Stone +4
Magnetic frustration, arising from the competition of exchange interactions, has received great attention because of its relevance to exotic quantum phenomena in materials. In the…

A nuclear quantum effect with pure anharmonicity and the anomalous thermal expansion of silicon
D. S. Kim, O. Hellman, J. Herriman +7
Despite the widespread use of silicon in modern technology, its peculiar thermal expansion is not well-understood. Adapting harmonic phonons to the specific volume at temperature,…

Phonon quarticity induced by changes in phonon-tracked hybridization during lattice expansion and its stabilization of rutile TiO
Tian Lan, C. W. Li, O. Hellman +5
Although the rutile structure of TiO is stable at high temperatures, the conventional quasiharmonic approximation predicts that several acoustic phonons decrease anomalously to…
