The black hole at the end of the cone: localizing the anomaly polynomial on toric geometries
Davide Cassani, Enrico Turetta
We consider five-dimensional supergravity coupled to vector multiplets, gauged or ungauged, and propose an efficient method to evaluate the on-shell action of supersymmetric black…
Gravitational index, black hole saddle degeneracy, and one-form symmetry
Davide Cassani, Gianmarco Esposto
It is known that the saddle describing the contribution of supersymmetric black holes to the index of four-dimensional superconformal field theories is degenerate. This degeneracy…
Bubbling saddles of the gravitational index
Davide Cassani, Alejandro Ruipérez, Enrico Turetta
We consider the five-dimensional supergravity path integral that computes a supersymmetric index, and uncover a wealth of semiclassical saddles with bubbling topology. These are co…
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…
