Scalar perturbations of black holes in Jackiw-Teitelboim gravity
Srijit Bhattacharjee, Subhodeep Sarkar, Arpan Bhattacharyya
We study linear scalar perturbations of black holes in two-dimensional (2D) gravity models with a particular emphasis on Jackiw-Teitelboim (JT) gravity. We obtain an exact expressi…
Displacement memory effect near the horizon of black holes
Srijit Bhattacharjee, Shailesh Kumar, Arpan Bhattacharyya
We study the displacement memory effect and its connection with the extended-BMS symmetries near the horizon of black holes. We show there is a permanent shift in the geodesic devi…
Memory effect and BMS symmetries for extreme black holes
Srijit Bhattacharjee, Shailesh Kumar
We study horizon shells and soldering freedom for extreme black holes and how supertranslation-like Bondi-Metzner-Sachs (BMS) symmetries appear as soldering transformations. Furthe…
