Abstract

The research status of the shear viscosity of nucleonic matter is reviewed. Some methods to calculate the shear viscosity of nucleonic matter are introduced, including mean free path, Green–Kubo, shear strain rate, Chapman–Enskog and relaxation time approximation. Based on these methods, results for infinite and finite nucleonic matter are discussed, which are attempts to investigate the universality of the ratio of shear viscosity over entropy density and transport characteristics like the liquid–gas phase transition in nucleonic matter. In addition, shear viscosity is also briefly discussed for the quantum chrodynamical matter produced in relativistic heavy-ion collisions.

核子物质的剪切粘度

综述了核子物质剪切粘度的研究现状。介绍了一些计算核子物质剪切粘度的方法，包括平均自由路径法、格林-库勃法、剪切应变率法、查普曼-恩斯科格法和弛豫时间近似法。在这些方法的基础上，讨论了无限核子物质和有限核子物质的结果，试图研究核子物质中剪切粘度与熵密度之比以及液气相变等输运特性的普遍性。此外，还简要讨论了相对论重离子碰撞中产生的量子动力学物质的剪切粘度。

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.
