动态异质性的不同表征概述
Overview of different characterisations of dynamic heterogeneity
摘要：
动态不均匀性现在被认为是具有慢动态的无序材料中结构弛豫的一个中心方面，并且是过去十年中密集研究的焦点。在这里，我们描述了如何初始的，间接的观察动态异质性最近演变成定义明确的，定量的，统计特征，特别是通过使用高阶相关性和响应函数。我们强调最近的进展和开放的问题，在玻璃材料的动态异质性的表征。我们还讨论了现有工具的局限性，并描述了一些候选人为未来的研究，以获得更深入的了解的起源和性质的玻璃在无序系统。
英文摘要：
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.
