通货膨胀的比例因子势方法

The Scale Factor Potential Approach to Inflation

David Benisty, Eduardo I. Guendelman, Emmanuel N. Saridakis

摘要:

我们提出了一种新的方法来研究通货膨胀的模型独立的方式,特别是详细说明所涉及的可观的,通过引入的“标度因子潜力”。通过它的使用,人们可以立即确定通货膨胀结束,这对应于它的第一个(和全局)最小值。另外,我们用e-折叠数作为自变量,用它的对数表示暴胀观测量。作为一个例子,我们构建了一类新的标量势,可以导致所需的谱指数和张量标量比,即$n_s \approx 0.965$和$r \sim 10^{-4}$为60 $e$倍,与观察一致。

英文摘要:

We propose a new approach to investigate inflation in a model-independent way, and in particular to elaborate the involved observables, through the introduction of the "scale factor potential". Through its use one can immediately determine the inflation end, which corresponds to its first (and global) minimum. Additionally, we express the inflationary observables in terms of its logarithm, using as independent variable the e-folding number. As an example, we construct a new class of scalar potentials that can lead to the desired spectral index and tensor-to-scalar ratio, namely $n_s \approx 0.965$ and $r \sim 10^{-4}$ for 60 $e$-folds, in agreement with observations.
