Abstract

One of the many physical questions that have emerged from studies of heavy-ion collisions at RHIC and the LHC concerns the validity of hydrodynamic modelling at the very early stages, when the Quark–Gluon Plasma system produced is still far from isotropy. In this article we review the idea of far-from-equilibrium hydrodynamic attractors as a way to understand how the complexity of initial states of nuclear matter is reduced so that a hydrodynamic description can be effective.

超相对论性核碰撞中的流体动力学吸引子

在RHIC和LHC的重离子碰撞研究中出现了许多物理问题，其中一个问题涉及在早期阶段流体动力学建模的有效性，当时夸克-胶子等离子体系统产生的夸克-胶子等离子体系统仍远未达到各向同性。在这篇文章中，我们回顾了远平衡流体动力学吸引子的思想，以此来理解如何降低核物质初始状态的复杂性，从而使流体动力学描述能够有效。

期刊介绍： Taking the format of four issues per year, the journal Progress in Particle and Nuclear Physics aims to discuss new developments in the field at a level suitable for the general nuclear and particle physicist and, in greater technical depth, to explore the most important advances in these areas. Most of the articles will be in one of the fields of nuclear physics, hadron physics, heavy ion physics, particle physics, as well as astrophysics and cosmology. A particular effort is made to treat topics of an interface type for which both particle and nuclear physics are important. Related topics such as detector physics, accelerator physics or the application of nuclear physics in the medical and archaeological fields will also be treated from time to time.
