Johari-Goldstein heterogeneous dynamics in a model polymer
Abstract
The heterogeneous character of the Johari-Goldstein (JG) relaxation is evidenced by molecular-dynamics simulation of a model polymer system. A double-peaked evolution of dynamic heterogeneity (DH), with maxima located at JG and structural relaxation time scales, is observed and mechanistically explained. The short-time single-particle displacement during JG relaxation weakly correlates with the long-time one observed during structural relaxation.
