论文摘要
我们使用一般的Yang-mills型Lagrangian研究了庞加莱量规理论的轴向矢量扭转旋转耦合效应。 ``电动''和`磁场变量的``电''和`磁成分的动力学方程是以一般形式获得的,并且表明螺旋密度和电磁场的旋转密度显示为物理源。得出了电磁场的修改后的麦克斯韦方程,并考虑了均匀均匀扭转场作用下的电磁波传播。我们证明了对这种波的极化旋转旋转的效果,并从天体物理数据中建立了可能的宇宙轴向扭转场。
We investigate the axial vector torsion-spin coupling effects in the framework of the Poincaré gauge theory of gravity with the general Yang-Mills type Lagrangian. The dynamical equations for the ``electric'' and ``magnetic'' components of the torsion field variable are obtained in the general form and it is shown that the helicity density and the spin density of the electromagnetic field appear as the physical sources. The modified Maxwell's equations for the electromagnetic field are derived, and the electromagnetic wave propagation under the action of the uniform homogeneous torsion field is considered. We demonstrate the Faraday effect of rotation of the polarization for such a wave, and establish the strong bound on the possible cosmic axial torsion field from the astrophysical data.
