标题： Anisotropic pressure induced by finite-size effects in SU(3) Yang-Mills theory

摘要： 我们研究了在有限尺寸的各向异性系统中SU(3)杨-米尔斯理论在非零温度下的压力各向异性。在具有周期性边界条件且空间体积为各向异性的格点上进行了模拟。通过梯度流定义的能量动量张量被用于分析格点上的应力张量。我们发现，即使考虑到后者较大的质量，在与自由标量理论相比时，只有在显著更短的空间范围下才能观察到压力各向异性中的有限尺寸效应。 显示英文摘要

摘要： We study the pressure anisotropy in anisotropic finite-size systems in SU(3) Yang-Mills theory at nonzero temperature. Lattice simulations are performed on lattices with anisotropic spatial volumes with periodic boundary conditions. The energy-momentum tensor defined through the gradient flow is used for the analysis of the stress tensor on the lattice. We find that a clear finite-size effect in the pressure anisotropy is observed only at a significantly shorter spatial extent compared with the free scalar theory, even when accounting for a rather large mass in the latter.
