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…
Phonons in an Inhomogeneous Continuum: Vibrations of an Embedded Nanoparticle
Daniel B. Murray, Lucien Saviot
The spectrum of acoustic vibrational modes of an inhomogeneous elastic continuum are analyzed with application to a spherical nanoparticle embedded in an infinite glass block. The…
Comment on "Estimate of the vibrational frequencies of spherical virus particles"
Lucien Saviot, Daniel B Murray, Alain Mermet +1
This comment corrects some errors which appeared in the calculation of an elastic sphere eigenenergies. As a result, the symmetry of the mode having the lowest frequency is changed…
Effect of physical aging on the low-frequency vibrational density of states of a glassy polymer
E. Duval, L. Saviot, L. David +2
The effects of the physical aging on the vibrational density of states (VDOS) of a polymeric glass is studied. The VDOS of a poly(methyl methacrylate) glass at low-energy (<15 meV)…
