A new model with solitary waves: solution, stability and quasinormal modes
Surajit Basak, Poulami Dutta Roy, Sayan Kar
We construct solitary wave solutions in a dimensional massless scalar () field theory with a specially chosen potential . The equation governing perturbations about…

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…
