论文摘要

制定了一般相对论磁水动力学的新的非线性轴子扩展版本。该理论的自洽形式主义基于对新统一标量不变式的拉格朗日的引入,该标量不变,该标量不变,在麦克斯韦张量中是二次的,并且包含两个周期性功能(Axion)字段。整个构建的统一不变和详细的非线性理论是相对于两个对称性的不变的:首先,与轴突场的性质相关的离散对称性;其次,杰克逊的SO(2)类型的对称性固有的电磁固有。主题的子系统描述了流体动力流的速度四载体,是在Eckart的粘性热传导流体理论的框架中构建的。 Ansatz围绕介质的大电导率补充了轴支延伸的非线性法拉第,高斯和安培方程,这通常与电场消失有关。我们已经提出了两个本质上是新的非线性模型,在该框架中,有限的伪尺度(Axion)场的适当行为可以补偿异常的电导率,从而在磁性流动流中提供有限的电场(要与磁场成比例,要么与培养基旋转的培养基旋转)相比。

The new nonlinear axionically extended version of the general relativistic magnetohydrodynamics is formulated. The self-consistent formalism of this theory is based on the introduction into the Lagrangian of the new unified scalar invariant, which is quadratic in the Maxwell tensor, and contains two periodic functions of the pseudoscalar (axion) field. The constructed unified invariant and the elaborated nonlinear theory as a whole, are invariant with respect to two symmetries: first, the discrete symmetry associated with the properties of the axion field; second, the Jackson's SO(2) type symmetry intrinsic for the electromagnetism. The subsystem of the master equations, which describes the velocity four-vector of the hydrodynamic flow, is constructed in the framework of Eckart's theory of viscous heat-conducting fluid. The axionically extended nonlinear Faraday, Gauss and Ampere equations are supplemented by the ansatz about the large electric conductivity of the medium, which is usually associated with vanishing of the electric field. We have suggested two essentially new nonlinear models, in the framework of which the anomalous electric conductivity is being compensated by the appropriate behavior of the finite pseudoscalar (axion) field, providing the electric field in the magnetohydrodynamic flow to be finite (either to be proportional to the magnetic field, or to the angular velocity of the medium rotation)
