Effect of glass stability on the low frequency vibrations of vapor deposited glasses
I. Festi, E. Alfinelli, D. Bessas +8
Ultra-stable glasses prepared from the physical vapor deposition of organic molecules present a very low density of two-level states, the kind of glass defects that determine their…
Boson peak in covalent network glasses: Isostaticity and marginal stability
Hideyuki Mizuno, Tatsuya Mori, Giacomo Baldi +1
The boson peak (BP) stands as a key feature in understanding glasses and amorphous materials. It directly underlies their anomalous material properties, including thermal behaviors…
Vibrational dynamics of non-crystalline solids
Giacomo Baldi, Aldo Fontana, Giulio Monaco
The boson peak (BP) is an excess of vibrational states over the Debye law appearing at terahertz frequencies. It is found in all glasses and marks the crossover between the long-wa…
Relaxation dynamics induced in glasses by the absorption of hard X-ray photons
Giovanna Pintori, Giacomo Baldi, Beatrice Ruta +1
X-ray photon correlation is used to probe the slow dynamics of the glass-former B2O3 across the glass transition. In the undercooled liquid phase the decay times of the measured co…
Vibrational excitations in systems with correlated disorder
W. Schirmacher, B. Schmid, C. Tomaras +4
We investigate a -dimensional model ( = 2,3) for sound waves in a disordered environment, in which the local fluctuations of the elastic modulus are spatially correlated with…
The Raman coupling function in disordered solids: a light and neutron scattering study on glasses of different fragility
A. Fontana, F. Rossi, G. Viliani +2
We report new inelastic Raman and neutron scattering spectra for glasses with different degrees of fragility; the data are compared for each sample to obtain the Raman coupling fun…
