Dirac单极的(弱)引力场

The (Weak) Gravitational Field of a Dirac Monopole

E. Banyas, J. Franklin

摘要:

我们利用广义相对论的弱场极限建立了狄拉克粒子的引力可探测性,弱场极限可以从牛顿引力势出发,包括能量作为源。由此产生的电势(通过构造)与爱因斯坦广义相对论方程的两种不同解的弱场极限相匹配:一种与构成狄拉克弦的半无限螺线管中出现的磁场线单极喷雾相关联,另一种与螺线管本身的场能量源(狄拉克弦)相关联。弦的引力效应占主导地位,我们认为,狄拉克配置的主要强场贡献是一个半无限能量线,其GR解决方案是已知的。

英文摘要:

We establish the gravitational detectability of a Dirac monopole using a weak-field limit of general relativity, which can be developed from the Newtonian gravitational potential by including energy as a source. The resulting potential matches (by construction) the weak-field limit of two different solutions to Einstein's equations of general relativity: one associated with the magnetically monopolar spray of field lines emerging from the half-infinite solenoid that makes up the Dirac monopole, the other associated with the field-energetic source of the solenoid itself (the Dirac string). The string's gravitational effect dominates, and we suggest that the primary strong-field contribution of the Dirac configuration is that of a half-infinite line of energy, whose GR solution is known.
