宇宙加速与非线性电动力学

Universe acceleration and nonlinear electrodynamics

S. I. Kruglov

摘要:

考虑了一个新的非线性电动力学模型,该模型具有一个与重力耦合的维数参数$β$。我们证明了当非线性电磁场是引力场的源时,宇宙会加速膨胀。研究了一个纯磁宇宙,磁场驱动宇宙加速运动。在这个模型中,在大爆炸之后,宇宙经历暴胀,加速膨胀,然后减速渐近地接近闵可夫斯基时空。我们证明了因果关系的模型和经典的稳定性在减速阶段。

英文摘要:

A new model of nonlinear electrodynamics with a dimensional parameter $β$ coupled to gravity is considered. We show that an accelerated expansion of the universe takes place if the nonlinear electromagnetic field is the source of the gravitational field. A pure magnetic universe is investigated and the magnetic field drives the universe to accelerate. In this model, after the big bang, the universe undergoes inflation, and the accelerated expansion and then decelerates approaching Minkowski spacetime asymptotically. We demonstrate the causality of the model and a classical stability at the deceleration phase.
