abstract

We refine and extend a recent construction of sets of black hole microstates with semiclassical interiors that span a Hilbert space of dimension $e^S$, where $S$ is the black hole entropy. We elaborate on the definition and properties of microstates in statistical and black hole mechanics. The gravitational description of microstates employs matter shells in the interior of the black hole, and we argue that in the limit where the shells are very heavy, the construction acquires universal validity. To this end, we show it for very wide classes of black holes: we first extend the construction to rotating and charged black holes, including extremal and near-extremal solutions, with or without supersymmetry, and we sketch how the construction of microstates can be embedded in String Theory. We then describe how the approach can include general quantum corrections, near or far from extremality. For supersymmetric black holes, the microstates we construct differ from other recent constructions in that the interior excitations are not confined within the near-extremal throat.

  1. Microstate counting from defects in de Sitter

    hep-th 2025-11 conditional novelty 6.0 of 10

    Counting defect microstates via Lorentzian wormholes reproduces the de Sitter and Schwarzschild-de Sitter entropy area laws.

  2. Flow-geometry microstates

    hep-th 2025-10 conditional novelty 6.0 of 10

    Particle-insertion microstates in AdS2→dS2 flow geometries are counted via wormhole path integrals, giving a Hilbert-space dimension e^{2S_Flow} that matches Gibbons-Hawking; the purely-de Sitter spanning claim depend...

  3. How to Count States in Gravity

    hep-th 2025-06 conditional novelty 6.0 of 10

    The Gibbons-Hawking Euclidean gravity path integral with periodic time equals an explicit thermal trace over the single-boundary quantum gravity Hilbert space.

    hep-th 2025-06 conditional novelty 6.0 of 10

    Spinning and higher-point thin-shell operator correlators in AdS3/CFT2 are shown to match across ETH analysis, the vacuum Virasoro block, and gravitational on-shell actions, with order-dependent structure for multiple...

  5. The Baby Universe is Fine and the CFT Knows It: On Holography for Closed Universes

    hep-th 2025-07 conditional novelty 5.0 of 10

    A closed universe in AdS/CFT is not ruled out by recent SWAP-test arguments; the one-dimensional Hilbert space seen from the CFT is external indistinguishability, and CFT data can reconstruct the closed universe's geometry.

  6. Black Holes, Entanglement and Decoherence

    hep-th 2025-08 unverdicted novelty 2.0 of 10

    Satishchandran reviews three equivalent mechanisms by which black holes and other Killing horizons decohere nearby quantum superpositions, via interior entanglement, soft radiation, and fluctuating multipoles.
