Title |
Superconformal index and gravitational path-integral |
|
Abstract |
AdS/CFT provides a consistent non-perturbative definition of quantum gravity in
asymptotically AdS spacetimes. Black holes should correspond to ensembles of
states in the boundary field theory. By performing a careful analysis of the
superconformal index of 4d N=4 SU(N) Super-Yang-Mills theory, with the help of a
Bethe Ansatz type formula, we are able to exactly reproduce the Bekenstein-Hawking
entropy of BPS black holes in AdS5 x S5. The large N limit exhibits many competing
contributions, that we are able to identify with complex saddles of the (putative)
gravitational path-integral. Along the way we propose a necessary condition for
complex saddles to contribute, based on the size of their non-perturbative
corrections. Such a prescription exactly matches the field theory analysis. |
