本研究在扩展引力与电动力学框架下,提出辐射巴丁黑洞作为暗物质候选体,其周围形成类似原子的引力-电磁结构,并限制磁场于特定距离内。
AI 中文摘要
我们在引力和电动力学的扩展模型框架内,考虑了一个具有可变质量和磁荷的巴丁黑洞(BBH),其中变分作用中的边界项被视为时空的几何量子涨落。我们提出扩展的黎曼流形是由一个新的联络$\u005chat{\delta\Gamma}^{\u005cmu}_{\alpha\beta}$生成的。这些联络分量包含了在由黎曼流形描述的弯曲背景度量上,关于引力与电磁涨落的几何信息。此外,我们利用引力和电磁势的非线性、非对易量子代数,计算了磁场分量的期望值。我们的结果与一个辐射的、有质量的磁单极子相一致,该磁单极子产生了一个径向磁场分量,该分量被限制在距离$r<\sqrt{3/\lambda_0}$内,此距离受真空能量密度限制。场$\hat{A}^{\mu}$描述了在BBH附近发现的有质量光子,它们形成了一个类似于原子的引力-电磁结构,这可能是早期宇宙中暗物质的候选体。
英文摘要
We consider a Bardeen black hole (BBH) with variable mass and magnetic charge within the framework of an extended model of gravity and electrodynamics, where the boundary terms in the varied action are treated as geometric quantum fluctuations of spacetime. We propose that the extended Riemann manifold is generated by a new connection, $\hat{δΓ}^μ_{αβ}$. These connection components contain geometric information regarding both gravitational and electromagnetic fluctuations on the background curved metric described by a Riemann manifold. Furthermore, we calculate the expectation values for the magnetic field components using a nonlinear and non-commutative quantum algebra for the gravitational and electromagnetic potentials. Our results are consistent with a radiating massive magnetic monopole that produces a radial component of the magnetic field confined to distances $r<\sqrt{3/λ_0}$, which are restricted by the vacuum energy density. The field $\hat{A}^μ$ describes massive photons found in the vicinity of a BBH, forming a gravito-electromagnetic structure analogous to that of an atom, which could be a candidate for dark matter in the early universe.
