Abstract:
This paper discusses the thermodynamics of a black hole with respect to Hawking radiation
and the entropy. We look at a unified picture of black hole entropy and curvature
and how this can lead to the usual black hole luminosity due to Hawking radiation. It is
also shown how the volume inside the horizon, apart from the surface area (hologram!),
can play a role in understanding the Hawking flux. In addition, holography implies a
phase space associated with the interior volume and this happens to be just a quantum
of phase space, filled with just one photon. The generalized uncertainty principle
can be incorporated in this analysis. These results hold for all black hole masses in any
dimension.
