全息宇宙学中的标量暖暴胀

Scalar warm inflation in holographic cosmology

Zahra Bouabdallaoui, Ahmed Errahmani, Mariam Bouhmadi-López, Taoufik Ouali

摘要:

我们在全息宇宙学的背景下考虑热膨胀。弱耗散和强耗散制度进行了分析,在慢滚近似和所谓的中间通货膨胀。在适当选择物态方程的情况下,中间暴胀不仅是广义相对论的精确解,而且也是本文所考虑的全息系统的精确解。在这种方法中,几个耗散和物理相关的功能被认为是。我们使用最新的普朗克数据来约束我们的模型。我们的结论是,三个模型分析与普朗克数据的模型参数的某些范围是一致的。然而,其中一个被观察排除在外。

英文摘要:

We consider warm inflation in the context of holographic cosmology. The weak and the strong dissipative regime are analysed in the slow-roll approximation and within what is known as intermediate inflation. For an appropriate choice of the equation of state, the intermediate inflation is not only an exact solution in general relativity, but also in the holographic setup considered in this paper. Within this approach several dissipative and physically relevant functions are considered. We constrain our model using the latest Planck data. We conclude that three of the models analysed are consistent with Planck data for some ranges of the model parameters. However, one of them is ruled out by the observations.
