Note on electromagnetic memories
arXiv:2105.06095 · doi:10.1103/PhysRevD.104.084026
Abstract
In this note, we provide a tractable example of a polyhomogeneous solution space for electromagnetism at null infinity in four dimensions. The memory effect for electromagnetism is then derived from the polyhomogeneous solution space. We also comment on the connection between the electromagnetic memories and asymptotic symmetries.
