Numerical simulation is employed to study dynamical heterogeneities in model monoatomic harmonic glasses, whose atoms interact trough the Lennard-Jones potential. Soft and hard vibrational heterogeneities are observed, and a temperature effect on these heterogeneities is found. A method is proposed to evaluate the size of the heterogeneities.

Abstract
Numerical simulation is employed to study dynamical heterogeneities in model monoatomic harmonic glasses, whose atoms interact trough the Lennard-Jones potential. Soft and hard vibrational heterogeneities are observed, and a temperature effect on these heterogeneities is found. A method is proposed to evaluate the size of the heterogeneities.File in questo prodotto:
