Sub-leading contributions to the black hole entropy in the brick wall approach
Sudipta Sarkar, S. Shankaranarayanan, L. Sriramkumar
[Abridged] We compute the canonical entropy of a quantum scalar field around static and spherically symmetric black holes through the brick wall approach at the higher orders (in f…
Hawking radiation as tunneling for spherically symmetric black holes: A generalized treatment
Sudipta Sarkar, Dawood Kothawala
We present a derivation of Hawking radiation through tunneling mechanism for a general class of asymptotically flat, spherically symmetric spacetimes. The tunneling rate $Γ\sim \ex…
Einstein's equations as a thermodynamic identity: The cases of stationary axisymmetric horizons and evolving spherically symmetric horizons
Dawood Kothawala, Sudipta Sarkar, T. Padmanabhan
There is an intriguing analogy between the gravitational dynamics of the horizons and thermodynamics. In case of general relativity, as well as for a wider class of Lanczos-Loveloc…
