Temperature-dependent vibrational heterogeneities in harmonic glasses

Disordered Systems and Neural Networks 2007-05-23 v1

Abstract

Numerical simulation is employed to study dynamical heterogeneities in model harmonic glasses whose atoms interact via three variants of the Lennard-Jones potential (monoatomic full Lennard-Jones, soft spheres, binary mixture). Heterogeneities are observed to exist in all three kinds of glasses, and in some cases they are observed to depend on temperature. The dimension of the heterogeneities is studied for the full Lennard-Jones case.
