We compute the supersymmetric index of half BPS black holes in N=2 supergravity with higher curvature corrections and show that the result agrees with the degeneracy of supersymmetric extremal black holes carrying the same charges. Both sides of the computation are done gravitationally.

  1. Multicentered black hole saddles for supersymmetric indices

    hep-th 2025-07 conditional novelty 7.0 of 10

    Multi-center black hole saddles for the supersymmetric index exist at finite temperature, their on-shell action is the sum of extremal entropies, and the entire moduli space of saddles vanishes at walls of marginal stability.

    hep-th 2026-06 unverdicted novelty 6.0 of 10

    Constructs index saddle for D1-D5-P black string via BPS limit and uplift, with decoupling to BTZ x S^3 computing CFT index.

  3. Index saddle for supersymmetric F1-P black ring

    hep-th 2026-01 conditional novelty 6.0 of 10

    A complex supergravity solution is identified as the index saddle of the F1–P small black ring; its higher-derivative corrections reproduce the microscopic index √(nw−JQ) up to an unfixed constant, in a restricted thi...

    Numerical confirmation of the attractor mechanism and 1/4 supersymmetry preservation for generic dyonic extremal black holes in pure N=4 supergravity.

  5. Gravitational index of the D1-D5-P black string

    hep-th 2026-07 conditional novelty 4.0 of 10

    Complex, supersymmetric, non-extremal Euclidean saddles for the D1-D5-P black string realize the gravitational index and match the Cardy formula of the dual elliptic genus.
