A comment on black hole state counting in loop quantum gravity
A. Ghosh, P. Mitra
There are two ways of counting microscopic states of black holes in loop quantum gravity, one counting all allowed spin network labels and the other involving only the labels…

Temperatures of extremal black holes
A. Ghosh, P. Mitra
The temperature of an extremal Reissner - Nordstrom black hole is not restricted by the requirement of absence of a conical singularity. It is demonstrated how Kruskal-like coordin…

Black hole entropy: departures from area law
P. Mitra
The thermodynamic and euclidean functional integral approaches to black hole entropy are discussed. The existence of some freedom in the definition of the entropy is pointed out an…
