Entropic route to Brown-York tensor: A unified framework for null and timelike hypersurfaces
Krishnakanta Bhattacharya, Bhera Ram, Bibhas Ranjan Majhi
Building on Padmanabhan's entropy functional, originally introduced to derive Einstein's equations and highlight the emergent nature of gravity, we demonstrate its robustness in a…
Generalized First Law and Smarr-type Relation: Beyond Additivity and Extensivity
Usman Zafar, Krishnakanta Bhattacharya, Kazuharu Bamba
In this work, we develop a general framework for deriving the first law of black hole thermodynamics and the associated Smarr-type relation for 4-dimensional static spherically sym…
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 (…
