论文摘要

标量场出现在许多宇宙学模型中,尤其是为了提供有关暗能量和通货膨胀的解释,但也可以模仿暗物质。在本文中,我们表明,标量场可以通过假设存在非最小耦合与重力,墨西哥帽子的潜力以及自发对称性破裂之前,可以同时替代暗物质,暗能量和通货膨胀。通货膨胀后,标量场的行为就像暗液,模仿了暗能量和暗物质,并且具有类似模糊的暗物质的暗物质行为。

Scalar fields appear in many cosmological models, in particular in order to provide explanations for dark energy and inflation, but also to emulate dark matter. In this paper, we show that it is possible for a scalar field to replace simultaneously dark matter, dark energy and inflation by assuming the existence of a non-minimal coupling to gravity, a Mexican hat potential, and a spontaneous symmetry breaking before inflation. After inflation, the scalar field behaves like a dark fluid, mimicking dark energy and dark matter, and has a dark matter behaviour similar to fuzzy dark matter.
