论文摘要
我们考虑轴心暗物质的分布以及在常规磁性单极的背景下轴子诱导的电场的曲线。背景静态球形对称时空被认为是在物体中心的规则，并且没有事件范围，强力引力和单极型磁场的非微小相互作用是来源，这提供了这种规律性。我们假设伪尺度（轴）场也非最小程度地耦合到电磁场和引力场，我们在非小轴静电仪的扩展方程中寻找解决方案，这满足了两个要求：首先，轴支轴线诱导的辐射电场在中心消失；其次，伪尺度场是在形成的轴子Dyon的中心定期的。我们发现了一组参数，描述了非最小轴 - 光子耦合，满足了这两个要求。数值分析了非最小轴静电方程的两参数溶液方程的特性。正常轴心诱导的电场显示具有结构，这对于简单的电层是典型的。
We consider the distribution of the axionic dark matter and the profiles of the axionically induced electric field on the background of a regular magnetic monopole. The background static spherically symmetric spacetime is considered to be regular at the center of the object and has no event horizons, the nonminimal interaction of strong gravitational and monopole type magnetic fields being the source, which provides this regularity. We assume that the pseudoscalar (axion) field also is nonminimally coupled to the electromagnetic and gravitational fields, and we search for solutions to the extended equations of nonminimal axion electrostatics, which satisfy two requirements: first, the axionically induced radial electric field vanishes at the center; second, the pseudoscalar field is regular at the center of the formed axionic dyon. We have found the set of parameters, describing the nonminimal axion-photon coupling, for which both requirements are satisfied. Properties of the two-parameter family of regular solutions to the equations of nonminimal axion electrostatics are analyzed numerically. The regular axionically induced electric field is shown to have the structure, which is typical for a simple electric layer.
