Dynamical interiors of Black-Bounce spacetimes
Kunal Pal, Kuntal Pal, Tapobrata Sarkar
Using the Israel-Darmois junction conditions, we obtain a class of regular dynamical interiors to the recently proposed black-bounce spacetimes which regularises the Schwarzschild…
Complexity in two-point measurement schemes
Ankit Gill, Kunal Pal, Kuntal Pal +1
We show that the characteristic function of the probability distribution associated with the change of an observable in a two-point measurement protocol with a perturbation can be…
Spread complexity evolution in quenched interacting quantum systems
Mamta Gautam, Kunal Pal, Kuntal Pal +3
We analyse time evolution of spread complexity (SC) in an isolated interacting quantum many-body system when it is subjected to a sudden quench. The differences in characteristics…
Geodesically completing regular black holes by the Simpson-Visser method
Kunal Pal, Kuntal Pal, Tapobrata Sarkar
Regular black holes are often geodesically incomplete when their extensions to negative values of the radial coordinate are considered. Here, we propose to use the Simpson-Visser m…
Tidal disruption of white dwarfs in a modified gravity theory with SPH
Debojyoti Garain, Pritam Banerjee, Shaswata Chowdhury +1
Low energy imprints of modifications to general relativity are often found in pressure balance equations inside stars. These modifications are then amenable to tests via astrophysi…
A rotating modified JNW spacetime as a Kerr black hole mimicker
Kunal Pal, Kuntal Pal, Rajibul Shaikh +1
The Event Horizon Telescope has recently observed the images and shadows of the compact objects M87 and Sgr A at the centres of the galaxies Messier 87 and Milky Way. This…
