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 anharmonicity and negative thermal expansion in SnSe
Dipanshu Bansal, Jiawang Hong, Chen W. Li +5
The anharmonic phonon properties of SnSe in the Pnma phase were investigated with a combination of experiments and first-principles simulations. Using inelastic neutron scattering…
Weak coupling of pseudoacoustic phonons and magnon dynamics in incommensurate spin ladder compound Sr14Cu24O41
Xi Chen, Dipanshu Bansal, Sean Sullivan +5
Intriguing lattice dynamics has been predicted for aperiodic crystals that contain incommensurate substructures. Here we report inelastic neutron scattering measurements of phonon…
