非零温度下夸克-反夸克和单夸克系统的应力分布
Stress distribution in quark--anti-quark and single quark systems at nonzero temperature
摘要：
本文推广了我们以前对真空中静态夸克-反夸克系统中的能量动量张量分布的研究，讨论了SU（3）Yang-Mills规范理论中非零温下夸克-反夸克和单夸克周围的能量动量张量分布.我们讨论了真空模拟中观察到的磁通管结构的消失。我们研究了作用在夸克和反夸克之间的中平面上的总应力，并表明它与由自由能的导数得到的力是一致的。根据EMT分布讨论了退精细相中的色德拜屏蔽效应。
英文摘要：
We explore the distribution of the energy momentum tensor (EMT) around quark--anti-quark and single quark at nonzero temperature in SU(3) Yang-Mills gauge theory by extending our previous study on the EMT distribution in static quark--anti-quark systems in vacuum. We discuss the disappearance of the flux tube structure observed in the vacuum simulation. We investigate the total stress acting on the mid-plane between a quark and an anti-quark and show that it agrees with the force obtained from the derivative of the free energy. The color Debye screening effect in the deconfined phase is also discussed in terms of the EMT distribution.
