我们计算有限温度修正的有效作用的共形不变标量场在均匀和轻微的各向异性时空。与T = 0的情况相比,有效作用量中的非定域项在保持粒子产生的总概率有限方面至关重要。
We calculate finite-temperature corrections to the effective action of the conformally invariant scalar field in a homogeneous and slightly anisotropic spacetime. The nonlocal term in the effective action is crucially important in keeping the total probability of particle production finite in contrast with the case at T = 0.
