标题： Squeezed Thermal State Representation of the Inflaton and Particle Production in Bianchi type-I Universe

摘要： 在本研究中，我们使用单模压缩热真空态形式，并在Bianchi类型-I宇宙的半经典引力框架下，研究了与引力最小耦合的质量均匀标量场的性质。 我们得到了半经典爱因斯坦方程的近似解，显示Bianchi类型-I宇宙中的每个尺度因子在其各自方向上遵循t^(2/3)幂律膨胀。 在Bianchi类型-I宇宙中也分析了非经典热宇宙粒子产生的机制。 显示英文摘要

摘要： 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.
