Grigera, T.S. ; Martín Mayor, Víctor ; Parisi, G. ; Verrocchio, P. | American Physical Society | 2001-08-20The topological nature of the disorder of glasses and supercooled liquids strongly affects their high-frequency dynamics. In order to understand its main features, we analytically studied a simple topologically disordered model, where the partic[...]texto impreso
Grigera, T.S. ; Martín Mayor, Víctor ; Parisi, G. ; Verrocchio, P. | IOP publishing ltd | 2002-03-11We study numerically and analytically a simple off-lattice model of scalar harmonic vibrations by means of Euclidean random matrix theory. Since the spectrum of this model shares the most puzzling spectral features with the high-frequency domain[...]
