论文摘要
基于2018年比率重力的工作，该功能假设交叉比与重力的物理模型相关的变形，我们开发了一种生成动力学暗能量的机制 - 一种典型的黑暗场和重力。这种模型在早期和晚期宇宙中导致黑暗能量的行为不同。在以辐射为主的时代和以物质为主导的时代中，典型场的相关分析解决方案具有有趣的特性 - 从恒定场开始，然后随着宇宙扩展而振荡。通过马尔可夫链蒙特卡洛（Monte Carlo）在贝叶斯框架中使用本地测量（类型IA超新星）搜索参数空间，{H_0}（1σ）的探测范围与{H_0}（1σ）内的探测范围重叠了{H_0}值从Planck CMB CMB CMB Dataset推出的{H_0}（在1σ之内）。
Based on the work of ratio gravity developed in 2018, which postulates the deformation of the cross ratio to associate with the physical model of gravity, we develop a mechanism to generate dynamical dark energy - a quintessence field coupled with gravity. Such model causes the dark energy behaving differently in early and late time universe. In the radiation-dominated-era and matter-dominated-era, the related analytical solutions of the quintessence field have an interesting property - starting as a constant field, then oscillating as the universe expands. By Markov Chain Monte Carlo search of the parameter space with the local measurement (Type Ia supernovae) in the Bayesian framework, the probed range of {H_0} (within 1σ) overlaps the {H_0} value inferred from Planck CMB dataset by ΛCDM model.
