圈量子宇宙学中的暴胀概率

Probability of inflation in Loop Quantum Cosmology

Suzana Bedić, Gregory Vereshchagin

摘要:

讨论了在有质量标量场的圈量子宇宙学中如何定义宇宙演化的初始条件,以及反弹的存在如何影响该理论中暴胀的几率,并与广义相对论进行了比较.本文的主要发现是在宇宙的收缩阶段存在一个吸引子,这导致在反弹时的特殊条件,在遥远的过去,相当独立的初始条件的测量,因此非常具体的持续时间的暴胀阶段的e-折叠数约$140$。

英文摘要:

We discuss how initial conditions for cosmological evolution can be defined in Loop Quantum Cosmology with massive scalar field and how the presence of the bounce influences the probability of inflation in this theory, compared with General Relativity. The main finding of the paper is existence of an attractor in the contracting phase of the universe, which results in special conditions at the bounce, quite independent on the measure of initial conditions in the remote past, and hence very specific duration of inflationary stage with the number of e-foldings about $140$.
