Memory Effect for deformed gravitational waves
P. -M. Zhang, M. Elbistan, P. A. Horvathy
Abstract
Deformations of sandwich gravitational waves are considered. Squeezing a wave with pure displacement (DM) parameters to an impulsive wave, the DM property is lost, leaving us with the velocity effect (VM). For each fixed value of the deformation parameter p, DM can be restored by further increasing the amplitude which however diverge when p∞, and no impulsive wave is obtained.
