暴胀与新宇宙学暗能量

Inflation and New Agegraphic Dark Energy

Cheng-Yi Sun, Rui-Hong Yue

摘要:

在本文中,我们将对新年龄暗能量(NADE)模型的讨论扩展到包括暴胀阶段。通常,在充气模型中,为了方便,在充气结束时将共形时间$η$设置为零。由于$η=0$表示NADE的分歧,因此这与NADE模型不相容。为了避免这个困难,我们可以将共形时间重新定义为$η+δ$。然而,我们发现,正常数$δ$必须如此之大,NADE不能成为目前的优势。

英文摘要:

In the note, we extend the discussion of the new agegraphic dark energy (NADE) model to include the inflation stage. Usually, in the inflation models, for convenience the conformal time $η$ is set to be zero at the end of inflation. This is incompatible with the NADE model since $η=0$ indicates the divergence of NADE. To avoid the difficulty, we can redefine the conformal time as $η+δ$. However, we find that the positive constant $δ$ must be so large that NADE can not become dominated at present time.
