abstract = "The role of dynamic cooperativity and heterogeneity in structural relaxation remains a great puzzle. We present estimates of the dynamic heterogeneity length scale ξ in many glass forming systems obtained using 4-D NMR, derivative analysis of two-points correlation function and the boson peak vibrations. Our analysis shows that ξ does not correlate to fragility of the system, while it correlates well to the sensitivity of structural relaxation to density. As the next step we discuss a relationship between dynamic heterogeneity and decoupling of diffusion from structural relaxation. We emphasize the problem of this approach in explaining recent data on decoupling phenomena. In the conclusion we suggest a general scenario for the dynamic heterogeneity and their role in structural relaxation.",
