用能量-动量张量探索非阿贝尔规范理论;应力、热力学和关联

Exploring non-Abelian gauge theory with energy-momentum tensor; stress, thermodynamics and correlations

Masakiyo Kitazawa

摘要:

我们执行各种晶格数值分析的能量动量张量(EMT)通过梯度流定义。我们研究了静态夸克-反夸克系统的应力张量和非零温度下的热力学量的空间分布,以及EMT的关联函数。研究了Abelian-Higgs模型中的应力张量分布,并与格点结果进行了比较。

英文摘要:

We perform various lattice numerical analyses with the energy-momentum tensor (EMT) defined through the gradient flow. We explore the spatial distribution of the stress tensor in static quark-anti-quark systems and thermodynamic quantities at nonzero temperature, as well as the correlation functions of EMT. The stress tensor distribution is also studied in the Abelian-Higgs model, which is compared with the lattice result.
