论文摘要
我们的主要目的是从基本的拉格朗日动作第一原理中构建一个合理的通货膨胀，暗能量和暗物质的统一模型，在该原理中，所有基本成分都是系统地生成动态产生的，从一种非常简单的修改重力模型与单个标量域相互作用，该模型与单个标量场相互作用，该模型采用了非帝国空间体积体积元素的形式。初始标量场作用中的非瑞曼体积元素导致隐藏的非线性对称性，该对称性产生能量弹药张量，被识别为动态生成的宇宙学常数和类似灰尘的暗物质的总和。传递到物理爱因斯坦 - 框架后，初始爱因斯坦 - 希尔伯特作用中的非瑞曼体积元素会动态产生第二个标量场场，具有非平凡的通货膨胀潜力，并与动态生成的暗物质有了额外的相互作用。由此产生的爱因斯坦 - 框架作用描述了一个完全动态生成的通货膨胀模型，结合了暗物质。可观察到的数值结果，例如标量功率谱指数和张量表与尺度的比率符合最新的2018 Planck数据。
Our primary objective is to construct a plausible unified model of inflation, dark energy and dark matter from a fundamental Lagrangian action first principle, where all fundamental ingredients are systematically dynamically generated starting from a very simple model of modified gravity interacting with a single scalar field employing the formalism of non-Riemannian spacetime volume-elements. The non-Riemannian volume element in the initial scalar field action leads to a hidden nonlinear Noether symmetry which produces energy-momentum tensor identified as a sum of a dynamically generated cosmological constant and a dust-like dark matter. The non-Riemannian volume-element in the initial Einstein-Hilbert action upon passage to the physical Einstein-frame creates dynamically a second scalar field with a non-trivial inflationary potential and with an additional interaction with the dynamically generated dark matter. The resulting Einstein-frame action describes a fully dynamically generated inflationary model coupled to dark matter. Numerical results for observables such as the scalar power spectral index and the tensor-to-scalar ratio conform to the latest 2018 PLANCK data.
