引力电磁效应在微观物理学中的某些结果

Some Consequences of Gravitationally Induced Electromagnetic Effects in Microphysics

Kjell Rosquist

摘要:

我们讨论引力场和电磁场之间的关系,由爱因斯坦-麦克斯韦场方程组。强调了引力场诱发电磁效应的趋势随着系统尺寸的减小而增大。特别是,根据广义相对论,在康普顿波长量级的距离上,引力场倾向于由自旋主导。控制这种行为的相关量是S/M^2,其中S是(自旋)角动量。对于一个电子,S/M^2 ~ 10^44。因此,重磁效应将在亚原子领域发挥重要作用。为了分析这种情况,我们使用多极场形式的渐近结构。指出了自旋带电粒子电磁场的一些重要结论。特别地,引力场可以引起对库仑场的修正,这可以通过实验来测试。

英文摘要:

We discuss the relation between the gravitational and electromagnetic fields as governed by the Einstein-Maxwell field equations. It is emphasized that the tendency of the gravitational field to induce electromagnetic effects increases as the size of the system goes down. In particular, the gravitational field, according to general relativity, tends to become dominated by the spin at distances of the order of the Compton wavelength. The relevant quantity which governs this behavior is the ratio S/M^2 where S is the (spin) angular momentum. For an electron, S/M^2 ~ 10^44. Therefore, gravitomagnetic effects will play a significant role in the subatomic domain. To analyze this situation we use the asymptotic structure in the form of the multipole fields. Some important consequences for the electromagnetic fields of charged particles with spin are pointed out. In particular, the gravitational field may induce corrections to the Coulomb field which can be tested experimentally.
