论文摘要
提出了一种具有尺寸参数$β$和$γ$的非线性电动力学的新模型。研究了因果关系的原则。我们表明,没有电荷来源的电场的奇异性是不存在的,并且中心的电场的最大值为$ e(0)= 1/\sqrtβ$。双重对称性在我们的模型中被打破。 $ r \ rightarrow \ infty $对库仑法的更正为$ {\ cal o}(r^{ - 4})$。引力场和宇宙通胀的来源是电磁场。据认为,宇宙被随机磁场填充。我们证明,在宇宙通货膨胀之后,宇宙减速了接近Minkowski时空。 Ricci标量,Ricci张量平方和Kretschmann标量的奇异性不存在。我们计算声音速度。评估了频谱指数,张量比比率和光谱指数的运行,该频谱指数与木板和WMAP数据大致一致。
A new model of nonlinear electrodynamics with dimensional parameters $β$ and $γ$ is proposed. The principles of causality and unitarity are studied. We show that a singularity of the electric field at the origin of charges is absent and the maximum of the electric field in the center is $E(0)=1/\sqrtβ$. The dual symmetry is broken in our model. Corrections to the Coulomb law as $r\rightarrow\infty$ are in the order of ${\cal O}(r^{-4})$. The source of the gravitation field and inflation of the universe is electromagnetic fields. It is supposed that the universe is filled by stochastic magnetic fields. We demonstrate that after the universe inflation the universe decelerates approaching the Minkowski spacetime. The singularities of the Ricci scalar, the Ricci tensor squared and the Kretschmann scalar are absent. We calculate the speed of sound. The spectral index, the tensor-to-scalar ratio, and the running of the spectral index, which approximately agree with the PLANK and WMAP data, are evaluated.
