Memory effect observables constructed in this manner are non-vanishing in typical scattering processes, which has implications for the asymptotic symmetry group.
WebOct 7, 2024 · Gravitational memory [ 14 – 20] is the classical change in nearby geodesics in an asymptotically flat region of space-time as they pass through an outgoing gravitational wave. A similar question has been addressed by Barrabes and Hogan [ 21, 22] where they studied the effect of a null shell on a time-like congruence that crosses it. WebMay 4, 2016 · The gravitational memory effect leads to a net displacement in the relative positions of test particles. This memory is related to the change in the strain of the gravitational radiation field between infinite past and infinite future retarded times. There are three known sources of the memory effect: (i) the loss of energy to future null infinity …
