Real-space Atomic Dynamics in Liquid Gallium Studied by Inelastic Neutron Scattering
Chengyun Hua, Yadu K. Sarathchandran, Eva Zarkadoula +4
Gallium is a prototypical liquid metal and has gained renewed attention due to its unique properties. Characterizing and elucidating its atomic dynamics remains elusive despite num…
Complexity in the medium-range order of gallium as a polyvalent liquid metal
Chengyun Hua, Yadu K. Sarathchandran, Eva Zarkadoula +4
Simplicity in chemical composition does not always translate into simplicity in the structures and dynamics of liquids and solids. Some elementary liquid metals, such as gallium, s…
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…
Discovery of coexisting Dirac and triply degenerate magnons in a three-dimensional antiferromagnet
Song Bao, Jinghui Wang, Wei Wang +11
Topological magnons are emergent quantum spin excitations featured by magnon bands crossing linearly at the points dubbed nodes, analogous to fermions in topological electronic sys…
