论文摘要

考虑了具有一般尺度因子的空间平坦的弗里德曼 - 罗伯逊步行者背景。在这个时空中,获得了带有一般曲率耦合参数的标量场的能量量张量。使用Thermo Field Dynamics(TFD)形式主义计算Stefan-Boltzmann定律和在有限温度下的Casimir效应。还考虑了在零温度下的casimir效应。宇宙的扩展改变了这些影响。提出了这些修改的讨论。

A spatially flat Friedmann-Robertson-Walker background with a general scale factor is considered. In this space-time, the energy-momentum tensor of the scalar field with a general curvature coupling parameter is obtained. Using the Thermo Field Dynamics (TFD) formalism the Stefan-Boltzmann law and the Casimir effect at finite temperature are calculated. The Casimir effect at zero temperature is also considered. The expansion of the universe changes these effects. A discussion of these modifications is presented.
