Kundt geometries and memory effects in the Brans-Dicke theory of gravity
Siddhant Siddhant, Indranil Chakraborty, Sayan Kar
Memory effects are studied in the simplest scalar-tensor theory, the Brans--Dicke (BD) theory. To this end, we introduce, in BD theory, novel Kundt spacetimes (without and with gyr…

Memory effects in Kundt wave spacetimes
Indranil Chakraborty, Sayan Kar
Memory effects in the exact Kundt wave spacetimes are shown to arise in the behaviour of geodesics in such spacetimes. The types of Kundt spacetimes we consider here are direct pro…

Geodesic congruences in exact plane wave spacetimes and the memory effect
Indranil Chakraborty, Sayan Kar
Displacement and velocity memory effects in the exact, vacuum, plane gravitational wave line element have been studied recently by looking at the behaviour of pairs of geodesics or…
