Gravitational and electromagnetic memory
arXiv:1912.01840 · doi:10.1103/PhysRevD.101.124015
Abstract
We present a unified investigation of memory effect in Einstein-Maxwell theory. We specify two types of memory effect, a velocity kick and a position displacement, by examining the motion of a single free falling charged test particle. Our result recovers the two known gravitational memory effect formulas and the two known electromagnetic memory effect formulas.
