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…
Thermodynamic parameters of fluids on conformally connected spacetimes
Bhera Ram, Bibhas Ranjan Majhi
Local thermal equilibrium generally implies the absence of heat flux within a fluid. We find the relations between a set of thermodynamic variables of a fluid on a general spacetim…
General relativistic heat flow from first order hydrodynamics
Bhera Ram, Bibhas Ranjan Majhi
Following the recently proposed stable and causal first-order relativistic hydrodynamics by Bemfica, Disconzi, and Noronha, we find the heat flow equation in the presence of gravit…
Laws of thermodynamic equilibrium within first order relativistic hydrodynamics
Bhera Ram, Bibhas Ranjan Majhi
Using recently developed consistent and robust first order relativistic hydrodynamics of a dissipative fluid we propose a generalization but weak version of Tolman-Ehrenfest relati…
