High order vibration modes of glass embedded AgAu nanoparticles
S. Adichtchev, S. Sirotkin, G. Bachelier +5
High resolution low frequency Raman scattering measurements from embedded AgAu nanoparticles unveil efficient scattering by harmonics of both the quadrupolar and the spherical mode…
Acoustic Nature of the Boson Peak in Vitreous Silica
C. Masciovecchio, V. Mazzacurati, G. Monaco +13
New temperature dependent inelastic x-ray (IXS) and Raman (RS) scattering data are compared to each other and with existing inelastic neutron scattering data in vitreous silica (v-…
Inelastic light, neutron, and X-ray scatterings related to the heterogeneous elasticity of glasses
E. Duval, L. Saviot, A. Mermet +4
The effects of plasticization of poly(methyl methacrylate) glass on the boson peaks observed by Raman and neutron scattering are compared. In plasticized glass the cohesion heterog…
Continuum elastic sphere vibrations as a model for low-lying optical modes in icosahedral quasicrystals
E. Duval, L. Saviot, A. Mermet +1
The nearly dispersionless, so-called "optical" vibrational modes observed by inelastic neutron scattering from icosahedral Al-Pd-Mn and Zn-Mg-Y quasicrystals are found to correspon…
Simple model for the vibrations of embedded elastically cubic nanocrystals
L. Saviot, D. B. Murray, E. Duval +3
The purpose of this work is to calculate the vibrational modes of an elastically anisotropic sphere embedded in an isotropic matrix. This has important application to understanding…
High frequency longitudinal and transverse dynamics in water
E. Pontecorvo, M. Krisch, A. Cunsolo +5
High-resolution, inelastic x-ray scattering measurements of the dynamic structure factor S(Q,Ï) of liquid water have been performed for wave vectors Q between 4 and 30 nm^-1 in di…
