玻璃体系中的涨落

Fluctuations in glassy systems

Claudio Chamon, Leticia F. Cugliandolo

摘要:

我们总结了一个理论框架的基础上,全球时间重新参数化的不变性,解释了玻璃态系统中的动态波动的起源。我们只介绍主要思想,不涉及太多技术细节。我们描述了从这种情况下产生的一些后果,可以测试的数值和实验区分那些也可以解释的其他机制,我们认为,是特殊的,我们的建议。我们支持我们的主张,提出了一些数值检查上进行的三维爱德华-安德森自旋玻璃。最后,我们讨论了在何种程度上这些想法适用于过冷液体,已经研究得更详细了。

英文摘要:

We summarize a theoretical framework based on global time-reparametrization invariance that explains the origin of dynamic fluctuations in glassy systems. We introduce the main ideas without getting into much technical details. We describe a number of consequences arising from this scenario that can be tested numerically and experimentally distinguishing those that can also be explained by other mechanisms from the ones that we believe, are special to our proposal. We support our claims by presenting some numerical checks performed on the 3d Edwards-Anderson spin-glass. Finally, we discuss up to which extent these ideas apply to super-cooled liquids that have been studied in much more detail up to present.
