论文摘要
在本文中，QCD是从三个不同方向研究的，其中一个总体主题：全息图。全息二元性允许用更简单的经典重力在一个维度上更多地描述某些强烈耦合的QFT。在本文中研究QCD的第一个方向是检查外部磁场对QCD特定全息模型的影响，从而产生有趣的定性见解。第二种方法研究了如何在同一模型中描述密集的重型构型，从而提供了一种研究组成中子星的物质的新方法。实际上，以这种方式产生的状态方程随后被用来计算可观察到的几种中子星特性，或者在不久的将来。最后一个方向本身不包含全息计算，但确实将全息图的几种定性见解纳入了一种称为轨迹的新的重离子代码。这将在不久的将来进行贝叶斯分析，希望可以在实验数据上测试这些全息图的定性见解，以了解来自全息图的想法与实验相匹配。
In this thesis, QCD is studied from three different directions, with one overarching theme: holography. The holographic duality allows certain strongly coupled QFTs to be described in terms of much simpler classical gravity in one dimension more. The first direction from which QCD is studied in this thesis is by examining the effects of an external magnetic field on a particular holographic model of QCD, yielding interesting qualitative insight. The second approach examines how, in the same model, one can describe dense baryonic configurations, providing a new way to study the matter composing neutron stars. Indeed, the equation of state produced in this way is subsequently used to compute several neutron star properties which are observable, or will be in the near future. The last direction contains no holographic computations per se, but does incorporate several qualitative insights from holography into a new heavy ion code called Trajectum. This will in the near future be used to perform a Bayesian analysis, whereby it is hoped that these qualitative insights from holography can be tested on experimental data, to see how well the ideas coming from holography match up with experiment.
