诱导暴胀的双吸引子行为

The double attractor behavior of induced inflation

Renata Kallosh, Andrei Linde, Diederik Roest

摘要:

我们描述了一类诱导暴胀模型,它是指具有广义非最小耦合$ξg(ϕ) R$和特定标量势的暴胀模型。这些模型的定义性质是,标量场在真空中采取一个vev,从而导致有效普朗克质量。我们研究这个模型作为耦合参数$ξ$的函数。在大$ξ$,理论的预测是已知的有吸引子行为,收敛到一个普遍的结果独立的功能$g(ϕ)$的选择。我们发现,在小$ξ$,理论的方法第二吸引子。这类理论的暴胀预言不断地在斯塔罗宾斯基模型的暴胀预言和具有二次势的最简单混沌暴胀预言之间插值。

英文摘要:

We describe an induced inflation, which refers to a class of inflationary models with a generalized non-minimal coupling $ξg(ϕ) R$ and a specific scalar potential. The defining property of these models is that the scalar field takes a vev in the vacuum and thus induces an effective Planck mass. We study this model as a function of the coupling parameter $ξ$. At large $ξ$, the predictions of the theory are known to have an attractor behavior, converging to a universal result independent on the choice of the function $g(ϕ)$. We find that at small $ξ$, the theory approaches a second attractor. The inflationary predictions of this class of theories continuously interpolate between those of the Starobinsky model and the predictions of the simplest chaotic inflation with a quadratic potential.
