早期宇宙:暴胀和宇宙学扰动

Early Universe: inflation and cosmological perturbations

David Langlois

摘要:

在简要概述了广义相对论和宇宙学之后,我们介绍了暴胀的基本概念,暴胀是目前早期宇宙最有动力的模型。我们描述了最简单的暴胀模型,基于一个单一的标量场,并讨论了原始的宇宙学扰动是如何产生的。然后,我们回顾了最近的发展有关的多场通货膨胀模型,特别是多场Dirac Born Infeld通货膨胀。

英文摘要:

After a brief summary of general relativity and cosmology, we present the basic concepts underlying inflation, the currently best motivated models for the early Universe. We describe the simplest inflation models, based on a single scalar field, and discuss how primordial cosmological perturbations are generated. We then review some recent developments concerning multi-field inflation models, in particular multi-field Dirac-Born-Infeld inflation.
