在Yang-Mills梯度流的基础上，研究了格点SU（3）规范理论中能量动量张量（EMT）的欧几里得两点相关器。由两点熵函数得到的熵密度和比热与由EMT单点函数得到的熵密度和比热吻合得很好。这些结果构成了第一步的第一原理模拟的输运系数与梯度流。
Euclidean two-point correlators of the energy-momentum tensor (EMT) in SU(3) gauge theory on the lattice are studied on the basis of the Yang-Mills gradient flow. The entropy density and the specific heat obtained from the two-point correlators are shown to be in good agreement with those from the one-point functions of EMT. These results constitute a first step toward the first principle simulations of the transport coefficients with the gradient flow.
