论文摘要
从慢速参数$ε$作为lorentzian形式作为e-folds $ n $的函数的假设中，获得了典型通货膨胀的成功模型，如\ cite {benisty：2020xqm}所简要研究。该形式对应于通货膨胀和黑暗能源时期的真空能量，并满足通货膨胀时期结束时从$ε$的小值到$ 1 $的条件。我们发现有两个平坦区域的相应标量典型通货膨胀势。此外，提出了一种加热机制，并对宇宙的均匀演化进行数值估计。建议的机制与BBN结合一致。
From the assumption that the slow roll parameter $ε$ has a Lorentzian form as a function of the e-folds number $N$, a successful model of a quintessential inflation is obtained, as succinctly studied in \cite{Benisty:2020xqm}. The form corresponds to the vacuum energy both in the inflationary and in the dark energy epochs and satisfies the condition to climb from small values of $ε$ to $1$ at the end of the inflationary epoch. We find the corresponding scalar Quintessential Inflationary potential with two flat regions. Moreover, a reheating mechanism is suggested with numerical estimation for the homogeneous evolution of the universe. The suggested mechanism is consistent with the BBN bound.
