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.

用模糊的暗液统一暗物质，暗能量和膨胀

标量场出现在许多宇宙学模型中，特别是为了提供暗能量和膨胀的解释，还为了模拟暗物质。在本文中，我们表明，标量场有可能通过假设存在与重力的最小耦合，墨西哥帽势和在充气之前自发对称破裂而同时替代暗物质，暗能量和充气。膨胀后，标量场的行为类似于暗流体，模仿暗能量和暗物质，并且具有类似于模糊暗物质的暗物质行为。
