摘要

摘要 在爱因斯坦-麦克斯韦-乙太轴理论框架内,我们考虑了一个基于两级控制概念的自洽模型,该模型由动态乙太对轴向活动电动系统的行为进行控制。该模型的拉格朗日包含两个指导函数,它们取决于乙太速度的四个微分不变式:乙太流的膨胀标量、加速度四矢量的平方、剪切张量和涡度张量的平方。第一种类型的引导函数是有效乙太度量的一个元素;这种有效度量参与了矢量场、伪标量场和电磁场的动力学项的表述,并预先确定了它们的演化特征。第二类指导函数与轴子的分布有关,描述其真空平均值;基本上,该函数出现在轴子场的势中,并预先确定其最小值的位置和深度。推导出了该模型的自洽耦合主方程组。一个静态球对称系统的例子被视为一个应用。

The Extended Einstein–Maxwell-Aether-Axion Theory: Effective Metric as an Instrument of the Aetheric Control over the Axion Dynamics

In the framework of the Einstein–Maxwell-aether-axion theory, we consider a self-consistent model based on the concept of two-level control, which is carried out by the dynamic aether over the behavior of an axionically active electrodynamic system. The Lagrangian of this model contains two guiding functions, which depend on four differential invariants of the aether velocity: the scalar of expansion of the aether flow, the square of the acceleration four-vector, the squares of the shear and vorticity tensors. The guiding function of the first type is an element of the effective aetheric metric; this effective metric is involved in the formulation of kinetic terms for the vector, pseudoscalar and electromagnetic fields and predetermines features of their evolution. The guiding function of the second type is associated with the distribution of axions and describes its vacuum average value; basically, this function appears in the potential of the axion field and predetermines the position and depth of its minima. The self-consistent set of coupled master equations of the model is derived. An example of a static spherically symmetric system is considered as an application.

期刊介绍: Gravitation and Cosmology is a peer-reviewed periodical, dealing with the full range of topics of gravitational physics and relativistic cosmology and published under the auspices of the Russian Gravitation Society and Peoples’ Friendship University of Russia. The journal publishes research papers, review articles and brief communications on the following fields: theoretical (classical and quantum) gravitation; relativistic astrophysics and cosmology, exact solutions and modern mathematical methods in gravitation and cosmology, including Lie groups, geometry and topology; unification theories including gravitation; fundamental physical constants and their possible variations; fundamental gravity experiments on Earth and in space; related topics. It also publishes selected old papers which have not lost their topicality but were previously published only in Russian and were not available to the worldwide research community
