任意维Maxwell理论在空间无穷远的渐近对称性

Asymptotic Symmetries of Maxwell Theory in Arbitrary Dimensions at Spatial Infinity

Erfan Esmaeili

摘要:

利用$d\geq 3$对Minkowski空间无穷远处的Maxwell理论进行了渐近对称性分析。我们重新审视de Sitter切片中的作用原理,并通过渐近规范固定使其得到很好的定义。因此,守恒电荷可以通过操纵作用量的表面项直接推导出来。值得注意的是,德西特空间上的对映条件是由$d\geq 4$在光锥处的场强的规律性所强加的。我们还展示了这个条件如何再现和推广的奇偶校验条件的惯性观察员在3+1配方。讨论了两种极限情形下荷的表达式:无穷大和惯性Minkowski观测器。对于单独处理的三维理论,通过一个大的推进极限,导出了零无穷远处的一组非对数边界条件。

英文摘要:

The asymptotic symmetry analysis of Maxwell theory at spatial infinity of Minkowski space with $d\geq 3$ is performed. We revisit the action principle in de Sitter slicing and make it well-defined by an asymptotic gauge fixing. In consequence, the conserved charges are inferred directly by manipulating surface terms of the action. Remarkably, the antipodal condition on de Sitter space is imposed by demanding regularity of field strength at light cone for $d\geq 4$. We also show how this condition reproduces and generalizes the parity conditions for inertial observers treated in 3+1 formulations. The expression of the charge for two limiting cases is discussed: Null infinity and inertial Minkowski observers. For the separately-treated 3d theory, a set of non-logarithmic boundary conditions at null infinity are derived by a large boost limit.
