On the Decay of Localized Vibrational States in Glasses: a one-dimensional example
Jaroslav Fabian
Abstract
The interaction between three localized vibrational modes is shown to be as relevant for the lifetimes of localized modes as the interaction involving two localized and one extended, and one localized and two extended modes. This contrasts with previous views. I support my arguments by a numerical study of a strongly disordered linear atomic chain.
