In this work, we propose an economical model to address some open cosmological problems such as the absence of the initial cosmological singularity, an early acceleration of the Universe and the generation of matter–antimatter asymmetry. The model is based on a scenario in which the early Universe consists of a non-linear electrodynamics (NLED) fields. It is found that the NLED model has an equation of state which shows that the Universe undergoes an early epoch acceleration to a radiation era given by . We show that the singularities in the energy density, pressure and curvature are absent at early stages. In our scenario, the baryon asymmetry is generated by the non-linearity parameter β. Additionally, we calculate the resulting baryon asymmetry and discuss how a successful gravitational baryogenesis is obtained for different values of the model’s parameter space.

在这项工作中，我们提出了一个经济模型来解决一些开放的宇宙学问题，例如初始宇宙奇点的缺失、宇宙的早期加速以及物质-反物质不对称的产生。该模型基于早期宇宙由非线性电动力学 (NLED) 场组成的场景。发现 NLED 模型有一个状态方程，表明宇宙经历了早期的时代加速到由 给出的辐射时代。我们表明，在早期阶段不存在能量密度、压力和曲率的奇点。在我们的场景中，重子不对称性由非线性参数β 生成. 此外，我们计算了由此产生的重子不对称性，并讨论了如何针对模型参数空间的不同值获得成功的引力重子发生。
