Gravitational Memory: an approximate description
arXiv:2609.39694
Abstract
The large-distance behaviour of a sandwich gravitational wave can be approximated by a continuous but not necessarily smooth profile, providing us with a simplified description of particle motion. Our approximate model is consistent with the Carroll symmetry. Our strategy is illustrated by the Poschl-Teller profile. The limits of the sandwich approximation are discussed.
