Decoupling saddles of the gravitational index and the Farey tail
Davide Cassani, Alejandro Ruipérez, Enrico Turetta
We first construct general saddles of the five-dimensional gravitational supersymmetric index with asymptotics, carrying an arbitrary number of electric cha…
Localization of the 5D supergravity action and Euclidean saddles for the black hole index
Davide Cassani, Alejandro Ruipérez, Enrico Turetta
We investigate equivariant localization of the gravitational on-shell action in odd dimensions, focusing on five-dimensional ungauged supergravity. We analyze the conditions for ca…
Non-spinning tops are stable
Iosif Bena, Giorgio Di Russo, Jose Francisco Morales +1
We consider coupled gravitational and electromagnetic perturbations of a family of five-dimensional Einstein-Maxwell solutions that describes both magnetized black strings and hori…
Higher-derivative corrections to flavoured BPS black hole thermodynamics and holography
Davide Cassani, Alejandro Ruipérez, Enrico Turetta
A Cardy-like regime of the four-dimensional superconformal index has been shown to be governed by 't Hooft anomalies and to single out a large- saddle carrying the Bekenstein-Ha…
Revisiting corrections to heterotic two-charge black holes
Stefano Massai, Alejandro Ruipérez, Matteo Zatti
We find solutions of the heterotic string effective action describing the first-order corrections to two-charge black holes at finite temperature. Making explicit use of these…
