abstract

We study the gravitational description of extremal supersymmetric black holes. We point out that the $AdS_2$ near horizon geometry can be used to compute interesting observables, such as correlation functions of operators. In this limit, the Hamiltonian is zero and correlation functions are time independent. We discuss some possible implications for the gravity description of black hole microstates. We also compare with numerical results in a supersymmetric version of SYK. These results can also be interpreted as providing a construction of wormholes joining two extremal black holes. This is the short version of a longer and more technical companion paper arXiv:2207.00408.

  1. The evaporation of black holes in supergravity

    hep-th 2025-04 conditional novelty 8.0 of 10

    Near-BPS black holes in N=2 supergravity emit a discrete spectral line when transitioning to BPS states, and their radiation and absorption spectra deviate strongly from semiclassical black-body predictions.

  2. Fortuity and fragility in supersymmetric SYK

    hep-th 2026-08 conditional novelty 6.0 of 10

    BPS classes in N=2 supersymmetric SYK are always continuable across system sizes along walks, but harmonic representatives generically fail to uplift exactly, and the paper's decoder quantifies this failure.

  3. Berry Picking: Random Wave Chaos Hierarchy for BPS Microstate Geometries

    hep-th 2026-07 conditional novelty 6.0 of 10

    Wave chaos in BPS microstate geometries strengthens toward black-hole-like throats while geodesic chaos weakens, and weak-coupling CFT Renyi entropies do not share that bulk hierarchy.
