This report summarizes the presentations and discussions during the Rapid Reaction Task Force “Dynamics of critical fluctuations: Theory – phenomenology – heavy-ion collisions”, which was organized by the ExtreMe Matter Institute EMMI and held at GSI, Darmstadt, Germany in April 2019. We address the current understanding of the dynamics of critical fluctuations in QCD and their measurement in heavy-ion collision experiments. In addition, we outline what might be learned from studying correlations in other physical systems, such as cold atomic gases.

临界波动的动力学：理论–现象学–重离子碰撞

本报告总结了由ExtreMe物质研究所EMMI组织并于2019年4月在德国达姆施塔特GSI举行的快速反应任务组“关键波动的动力学：理论–现象学–重离子碰撞”期间的演讲和讨论。我们讨论了当前对QCD临界波动动力学及其在重离子碰撞实验中的测量方法的理解。另外，我们概述了通过研究其他物理系统（例如冷原子气体）中的相关关系可以学到的东西。
