Chaotic Dynamics in Extremal Black Holes: A Challenge to the Chaos Bound
Surojit Dalui, Chiranjeeb Singha, Krishnakanta Bhattacharya
We investigate chaotic dynamics in extremal black holes by analyzing the motion of massless particles in both Reissner-Nordström and Kerr geometries. Two complementary approaches (…
Scalar-tensor theories of gravity from a thermodynamic viewpoint
Krishnakanta Bhattacharya, Sumanta Chakraborty
In any diffeomorphism invariant theory of gravity, one can define a Noether charge arising from the invariance of the Lagrangian under diffeomorphisms. We have determined the Noeth…
Radiating black hole solutions in arbitrary dimensions
S. G. Ghosh, A. K. Dawood
We prove a theorem that characterizes a large family of non-static solutions to Einstein equations in -dimensional space-time, representing, in general, spherically symmetric Ty…
Higher dimensional dust collapse with a cosmological constant
S. G. Ghosh, D. W. Deshkar
The general solution of the Einstein equation for higher dimensional (HD) spherically symmetric collapse of inhomogeneous dust in presence of a cosmological term, i.e., exact inter…
