Laws of Black Hole Mechanics from Holst Action
Ayan Chatterjee, Amit Ghosh
The formulation of Weak Isolated Horizons (WIH) based on the Isolated Horizon formulation of black hole horizons is reconsidered. The first part of the paper deals with the derivat…
Generic weak isolated horizons
Ayan Chatterjee, Amit Ghosh
Weak isolated horizon boundary conditions have been relaxed supposedly to their weakest form such that both zeroth and the first law of black hole mechanics still emerge, thus maki…
An improved estimate of black hole entropy in the quantum geometry approach
A. Ghosh, P. Mitra
A proper counting of states for black holes in the quantum geometry approach shows that the dominant configuration for spins are distributions that include spins exceeding one-half…
On the log correction to the black hole area law
Amit Ghosh, P. Mitra
Various approaches to black hole entropy yield the area law with logarithmic corrections, many involving a coefficient 1/2, and some involving 3/2. It is pointed out here that the…
