A Foundation Model for Non-Destructive Defect Identification from Vibrational Spectra
Mouyang Cheng, Chu-Liang Fu, Bowen Yu +5
Defects are ubiquitous in solids and strongly influence materials' mechanical and functional properties. However, non-destructive characterization and quantification of defects, es…
Diffuse Inelastic Neutron Scattering from Anharmonic Vibrations in Cuprite
C. N. Saunders, V. V. Ladygin, D. S. Kim +5
Atomic vibrational dynamics in cuprite, Cu2O, was studied by inelastic neutron scattering and molecular dynamics (MD) simulations from 10 K to 900 K. Above 300 K, a diffuse inelast…
Prediction and Observation of Intermodulation Sidebands from Anharmonic Phonons
Y. Shen, C. N. Saunders, C. M. Bernal +4
A quantum Langevin model, similar to models used recently for optomechanics, was used to predict intermodulation phonon sidebands (IPS). Ab initio calculations of anharmonic phonon…
Magnetic excitations from an S=1/2 diamond-shaped tetramer compound Cu2PO4OH
M. Matsuda, S. E. Dissanayake, D. L. Abernathy +2
Inelastic neutron scattering experiments have been carried out on a powder sample of Cu2PO4OH, which consists of diamond-shaped tetramer spin units with S=1/2. We have observed two…
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…
Inelastic neutron scattering study of phonon density of states in nanostructured Si1xGex thermoelectrics
Chetan Dhital, D. L. Abernathy, Gaohua Zhu +3
Inelastic neutron scattering measurements are utilized to explore relative changes in the generalized phonon density of states of nanocrystalline Si1xGex thermoelectric materials p…
