论文摘要
在这项研究中，我们使用单模挤压热真空状态形式主义，并检查一个巨大的同质标量场的性质，在比安奇类型I型宇宙中半经典重力的框架中与重力最小化。我们已经获得了Bianchi型宇宙的半经典爱因斯坦方程的估计领先解决方案，其各自方向的每个尺度因子都遵守t^（2/3）幂律的扩展。在Bianchi I型宇宙中，还分析了非经典宇宙学颗粒产生的机制。
In this study, we use a single-mode squeezed thermal vacuum state formalism and examine the nature of a massive homogeneous scalar field, minimally coupled to the gravity in the framework of semiclassical gravity in the Bianchi type-I universe. We have obtained an estimate leading solution to the semiclassical Einstein equation for the Bianchi type-I universe shows, each scale factor in its respective direction obeys t^(2/3) power-law expansion. The mechanism of the nonclassical thermal cosmological particle production is also analyzed in the Bianchi type-I universe.
