Velocity memory effect without soft particles
arXiv:1909.08414 · doi:10.1103/PhysRevD.101.024006
Abstract
We study the behavior of geodesics in the plane-fronted wave background of the three-dimensional (3D) gravity with propagating torsion, which possesses only massive degrees of freedom. We discover the velocity memory effect, in contrast to the current belief that its existence is due to the presence of soft particles.
