Evidence of two viscous relaxation processes in the collective dynamics of liquid lithium
T. Scopigno, U. Balucani, G. Ruocco +1
New inelastic X-ray scattering experiments have been performed on liquid lithium in a wide wavevector range. With respect to the previous measurements, the instrumental resolution,…
Intra-molecular origin of the fast relaxations observed in the Brillouin light scattering spectra of molecular glass-formers
G. Monaco, S. Caponi, R. Di Leonardo +2
The Brillouin light scattering spectra of the o-terphenyl single crystal are compared with those of the liquid and the glass phases. This shows: i) the direct evidence of a fast re…
The nature of the short wavelength excitations in vitreous silica: X-Rays Brillouin scattering study
O. Pilla, A. Cunsolo, A. Fontana +6
The dynamical structure factor (S(Q,E)) of vitreous silica has been measured by Inelastic X-ray Scattering varying the exchanged wavevector (Q) at fixed exchanged energy (E) - an e…
Collective dynamics of liquid aluminum probed by Inelastic X-ray Scattering
T. Scopigno, U. Balucani, G. Ruocco +1
An inelastic X-ray scattering experiment has been performed in liquid aluminum with the purpose of studying the collective excitations at wavevectors below the first sharp diffract…
Frustration and sound attenuation in structural glasses
L. Angelani, M. Montagna, G. Ruocco +1
Three classes of harmonic disorder systems (Lennard-Jones like glasses, percolators above threshold, and spring disordered lattices) have been numerically investigated in order to…
Relaxation processes in harmonic glasses?
G. Ruocco, F. Sette, R. Di Leonardo +4
A relaxation process, with the associated phenomenology of sound attenuation and sound velocity dispersion, is found in a simulated harmonic Lennard-Jones glass. We propose to iden…
