The nature of non-phononic excitations in disordered systems
Walter Schirmacher, Matteo Paoluzzi, Felix Cosmin Mocanu +4
Using heterogeneous-elasticity theory (HET) and a generalisation of HET theory (GHET), obtained by applying a newly developed procedure for obtaining the continuum limit of the gla…
Rayleigh anomalies and disorder-induced mixing of polarizations at nanoscale in amorphous solids. Testing 1-octyl-3-methylimidazolium chloride glass
Maria Grazia Izzo, Bjorn Wehinger, Stefano Cazzato +4
Acoustic excitations in topologically disordered media at mesoscale present anomalous features with respect to the Debye's theory. In a three-dimensional medium an acoustic excitat…
On the analysis of the vibrational Boson peak and low-energy excitations in glasses
S. N. Yannopoulos, K. S. Andrikopoulos, G. Ruocco
Implications of reduction procedures applied to the low energy part of the vibrational density of states in glasses and supercooled liquids are considered by advancing a detailed c…
Glassy behavior of light
L. Angelani, C. Conti, G. Ruocco +1
We study the nonlinear dynamics of a multi-mode random laser using the methods of statistical physics of disordered systems. A replica-symmetry breaking phase transition is predict…
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,ω) of liquid water have been performed for wave vectors Q between 4 and 30 nm^-1 in dis…
Low-energy excess of vibrational states in v-SiO2: the role of transverse dynamics
O. Pilla, A. Fontana, J. R. Goncalves +2
The study of the effects of the density variations on the vibrational dynamics in vitreous silica is presented. A detailed analysis of the dynamical structure factor, as well as of…
