Abstract

I will review the state of the art of the equation of state for strongly interacting matter from first principles. I will discuss results at zero and finite chemical potential. For the latter, I will focus on Taylor expansion, analytical continuation from imaginary chemical potential, and a novel expansion scheme that was recently introduced, and that allowed a substantial extension of the coverage in baryonic chemical potential. I will also introduce a few lattice-based approaches, used to study the thermodynamics in the vicinity of the critical point.

基于点阵模拟的QCD状态方程

我将从第一原理回顾强相互作用物质的状态方程的最新进展。我将讨论零化学势和有限化学势的结果。对于后者，我将重点介绍泰勒展开，从虚化学势出发的解析延拓，以及最近引入的一种新的展开方案，它允许重子化学势的覆盖范围得到实质性的扩展。我还将介绍一些基于晶格的方法，用于研究临界点附近的热力学。

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.
