早期宇宙的唯象模型

A Phenomenological Model for the Early Universe

N. C. Tsamis, R. P. Woodard

摘要:

我们认为,宇宙动力学的描述从一个完美的流体的参数必须是一致的,在膨胀过程中可能出现的增强的量子回路效应的强度的通货膨胀的开始。这些影响的来源必须是非本地的,它的一个简单的化身研究分析和数值。由此产生的演变停止通货膨胀在一个可计算的时间量,并导致一个振荡的宇宙与消失的平均值的曲率标量和振荡频率,我们计算。

英文摘要:

We consider the description of cosmological dynamics from the onset of inflation by a perfect fluid whose parameters must be consistent with the strength of the enhanced quantum loop effects that can arise during inflation. The source of these effects must be non-local and a simple incarnation of it is studied both analytically and numerically. The resulting evolution stops inflation in a calculable amount of time and leads to an oscillatory universe with a vanishing mean value for the curvature scalar and an oscillation frequency which we compute.
