老化系统中的增长长度尺度

Growing length scales in aging systems

Federico Corberi, Leticia F. Cugliandolo, Hajime Yoshino

摘要:

我们总结了在不同的老化系统中的增长长度的研究。文章的结构如下。我们回顾了一些可观测量的定义,通常是相关性和相关性,它们可以获得动态和静态相关长度。我们使用一个不断增长的长度的角度来看,审查三个平衡的情况下:域生长现象;爱德华-威尔金森和Kardar-Parisi-张流形和其他定向弹性流形在随机介质中的演变;自旋和结构玻璃在松弛和外部驱动下。最后,我们简要报告的机制,在老化系统中的动态波动,是基于一个时间重新参数化不变的情况下,可能是在玻璃材料的动态增长长度的起源。

英文摘要:

We summarize studies of growing lengths in different aging systems. The article is structured as follows. We recall the definition of a number of observables, typically correlations and susceptibilities, that give access to dynamic and static correlation lengths. We use a growing length perspective to review three out of equilibrium cases: domain growth phenomena; the evolution of Edwards-Wilkinson and Kardar-Parisi-Zhang manifolds and other directed elastic manifolds in random media; spin and structural glasses in relaxation and under an external drive. Finally, we briefly report on a mechanism for dynamic fluctuations in aging systems that is based on a time-reparametrization invariance scenario and may be at the origin of the dynamic growing length in glassy materials.
