The thermodynamic structure of Einstein tensor
Dawood Kothawala
We analyze the generic structure of Einstein tensor projected onto a 2-D spacelike surface S defined by unit timelike and spacelike vectors u_i and n_i respectively, which describe…
Thermodynamic structure of Lanczos-Lovelock field equations from near-horizon symmetries
Dawood Kothawala, T. Padmanabhan
It is well known that, for a wide class of spacetimes with horizons, Einstein equations near the horizon can be written as a thermodynamic identity. It is also known that the Einst…
Is gravitational entropy quantized ?
Dawood Kothawala, T. Padmanabhan, Sudipta Sarkar
In Einstein's gravity, the entropy of horizons is proportional to their area. Several arguments given in the literature suggest that, in this context, both area and entropy should…
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…
