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…
Modeling non-harmonic behavior of materials from experimental inelastic neutron scattering and thermal expansion measurements
Dipanshu Bansal, Amjad Aref, Gary Dargush +1
Based on thermodynamic principles, we derive expressions quantifying the non-harmonic vibrational behavior of materials, which are rigorous yet easily evaluated from experimentally…
