论文摘要
多样化的宇宙学和天体物理观测强烈暗示宇宙中存在暗物质和暗能量。宇宙学的主要目标之一是解释这两个组成部分的性质。暗物质和暗能量都有共同的起源。在本文中，我们开发了一个模型，在该模型中，由于两个相互作用的标量字段之间的相互作用而产生了黑暗扇区。使用混合膨胀电位，我们表明该模型可以描述为耦合到光标量磁场的无压流体系统。我们讨论了这种设置的宇宙学后果以及宇宙微波背景辐射和大规模结构中的观察性特征。
Diverse cosmological and astrophysical observations strongly hint at the presence of dark matter and dark energy in the Universe. One of the main goals of Cosmology is to explain the nature of these two components. It may well be that both dark matter and dark energy have a common origin. In this paper, we develop a model in which the dark sector arises due to an interplay between two interacting scalar fields. Employing a hybrid inflation potential, we show that the model can be described as a system of a pressureless fluid coupled to a light scalar field. We discuss this setup's cosmological consequences and the observational signatures in the cosmic microwave background radiation and the large-scale structures.
