Collective dynamics in molten potassium: an Inelastic X-ray Scattering study
A. Monaco, T. Scopigno, P. Benassi +5
The high frequency collective dynamics of molten potassium has been investigated by inelastic x-ray scattering, disclosing an energy/momentum transfer region unreachable by previou…
Potential Energy Landscape in Lennard-Jones binary mixture model
M. Sampoli, P. Benassi, R. Eramo +2
The potential energy landscape in the Kob-Andersen Lennard-Jones binary mixture model has been studied carefully from liquid down to the supercooled regime, from T =2 down to T =0.…
Non-Equilibrium Thermodynamic Description of the Coupling between Structural and Entropic Modes in Supercooled Liquids
R. Di Leonardo, A. Taschin, M. Sampoli +2
The density response of supercooled glycerol to an impulsive stimulated thermal grating (q=0.63 micron^-1) has been studied in the temperature range (T=200-340 K) where the structu…
Acoustic and relaxation processes in supercooled o-ter-phenyl by optical-heterodyne transient grating experiment
R. Torre, A. Taschin, M. Sampoli
The dynamics of the fragile glass-forming o-ter-phenyl is investigated by time-resolved transient grating experiment with an heterodyne detection technique in a wide temperature ra…
Translation-Rotation Coupling in Transient Grating Experiments : Theoretical and Experimental Evidences
A. Taschin, R. Torre, M. Ricci +3
The results of a Transient Grating experiment in a supercooled molecular liquid of anisotropic molecules and its theoretical interpretation are presented. These results show the ex…
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…
The Raman coupling function in amorphous silica and the nature of the long wavelength excitations in disordered systems
A. Fontana, R. Dell'Anna, M. Montagna +6
New Raman and incoherent neutron scattering data at various temperatures and molecular dynamic simulations in amorphous silica, are compared to obtain the Raman coupling coefficien…
High frequency sound waves in vitreous silica
R. Dell'Anna, G. Ruocco, M. Sampoli +1
We report a molecular dynamics simulation study of the sound waves in vitreous silica in the mesoscopic exchanged momentum range. The calculated dynamical structure factors are in…
