ORIGIN OF LIGHT SCATTERING FROM DISORDERED SYSTEMS
P. Benassi, W. Frizzera, M. Montagna +5
Anelastic light scattering is computed numerically for model disordered systems (linear chains and 2-dimensional site and bond percolators), with and without electrical disorder. A…
Absence of Definite Scaling Laws in Raman Scattering from Fractals
P. Benassi, O. Pilla, G. Viliani +4
The frequency dependence of the Raman coupling coefficient is calculated numerically for square and cubic percolation clusters. No general scaling law in terms of the macro…
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…
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-…
Sound attenuation in an unexplored frequency region: Brillouin Ultraviolet Light Scattering measurements in v-SiO2
P. Benassi, S. Caponi, R. Eramo +5
We report Ultraviolet Brillouin light scattering experimental data on v-SiO2 in an unexplored frequency region, performed with a newly available spectrometer up to exchanged waveve…
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.…
