Novel black saddles for 5d gravitational indices and the index enigma
Jan Boruch, Roberto Emparan, Luca V. Iliesiu +1
We construct a series of novel Euclidean multi-black-hole, black ring, black Saturn, and black lens solutions to supergravity that contribute as saddle-points to the grav…
Multicentered black hole saddles for supersymmetric indices
Jan Boruch, Luca V. Iliesiu, Sameer Murthy +1
The supersymmetric index in string theory can sometimes have a discontinuous integer-valued jump at co-dimension one surfaces in moduli space called walls of marginal stability. Wh…
Localization of strings on group manifolds
Sameer Murthy, Edward Witten
We compute the partition function of the WZW model with target a compact Lie group by adapting a method used by Choi and Takhtajan to compute the heat kernel of the group manif…
Strings and near-extremal black holes in theories with large superconformal symmetry
Sameer Murthy, Mukund Rangamani
We study the one-loop partition function of superstrings in the background. Specifically, we show that…
The gravitational index and allowable complex metrics
Pietro Benetti Genolini, Sameer Murthy
We study the Kontsevich-Segal-Witten criterion for allowable complex metrics, in the context of the gravitational path integral corresponding to the supersymmetric index. In variou…
Quantum black holes: supersymmetry and exact results
Davide Cassani, Sameer Murthy
The explanation of black hole entropy as statistical entropy is one of the big successes of string theory. In this article we review recent progress in this subject, focussing on u…
Localization and wall-crossing of giant graviton expansions in AdS
Giorgos Eleftheriou, Sameer Murthy, Martí Rosselló
The -BPS indices of Super Yang-Mills theory with unitary, orthogonal, and symplectic groups all admit -expansions suggesting an interpretation in terms…
The gravitational index of 5d black holes and black strings
Jan Boruch, Roberto Emparan, Luca V. Iliesiu +1
The supersymmetric index of 5d black strings and spinning black holes in M-theory is related to that of 4d black holes in type IIA supergravity when both theories are compactified…
