论文摘要

我们表明,在相对论的现场理论中,n个骨操作员的热相关函数<o_1(x_1,t_1)o_2(x_2,t_2,t_2).. o_n(x_n,t_n)>在足够空间分离的点上,分别分离时间符合分离的时间依赖时间变量。对于经典的热场理论,当所有点均分离时,时间依赖性消失

We show that, in relativistic field theories, the thermal correlation function of N bosonic operators <O_1(x_1,t_1) O_2(x_2,t_2) .. O_N(x_N,t_N)> at sufficiently spacelike-separated points shows exponentially weak dependence on the time variables t_1,...,t_N, when the space separations are held fixed. For classical thermal field theory, the time dependence vanishes when all points are spacelike separated
