论文摘要
研究了具有二维参数的非线性电动力学。当获得因果关系,单位性和经典稳定性的原理时,电磁场的范围。在我们的模型中,没有电荷中心的电场的奇异性,并且对库仑法律进行了纠正,为$ r \ rightarrow \ infty $。宇宙通胀发生在随机磁场的背景下。宇宙进化的第二阶段是辐射时代,因此优美的出口存在。我们估计了与Planck和WMAP数据粗略的频谱指数,张量与尺度比率以及光谱指数的运行。
Nonlinear electrodynamics with two dimensional parameters is studied. The range of electromagnetic fields when principles of causality, unitarity and the classical stability hold, are obtained. A singularity of the electric field at the center of charges is absent within our model and there are corrections to the Coulomb law as $r\rightarrow\infty$. The universe inflation takes place in the background of stochastic magnetic fields. The second stage of the universe evolution is the radiation era so that the graceful exit exists. We estimated the spectral index, the tensor-to-scalar ratio, and the running of the spectral index that are in a rough accord with the PLANCK and WMAP data.
