Abstract
The superconformal index of the supersymmetric Yang-Mills theory counts the -BPS (Bogomol’nyi-Prasad-Sommerfield) states in this theory, and has been used via the correspondence to count black hole microstates of -BPS black holes. On one hand, this index may be related to the Euclidean partition function of the theory on with complex chemical potentials, which maps by the correspondence to a sum over Euclidean gravity solutions. On the other hand, the index may be expressed as a sum over solutions to Bethe Ansatz (BA) equations. We show that the solutions to the BA equations that are known to have a good large limit, for the case of equal chemical potentials for the two angular momenta, have a one-to-one mapping to (complex) Euclidean black hole solutions on the gravity side. This mapping captures both the leading contribution from the classical gravity action (of order ), as well as nonperturbative corrections in , which on the gravity side are related to wrapped D3-branes. Some of the BA solutions map to orbifolds of the standard Euclidean black hole solutions (which obey exactly the same boundary conditions as the other solutions). A priori there are many more gravitational solutions than Bethe Ansatz solutions, but we show that, by considering the nonperturbative effects, the extra solutions are ruled out, leading to a precise match between the solutions on both sides.
