Abstract:
Dynamic heterogeneity is now recognised as a central aspect of structural relaxation in disordered materials with slow dynamics, and was the focus of intense research in the last decade. Here we describe how initial, indirect observations of dynamic heterogeneity have recently evolved into well-defined, quantitative, statistical characterisations, in particular through the use of high-order correlation and response functions. We highlight both recent progress and open questions about the characterisation of dynamic heterogeneity in glassy materials. We also discuss the limits of available tools and describe a few candidates for future research in order to gain deeper understanding of the origin and nature of glassiness in disordered systems.
