We construct an infinite family of microstates with geometric interiors for eternal black holes in general relativity with negative cosmological constant in any dimension. Wormholes in the Euclidean path integral for gravity cause these states to have small, but non-zero, quantum mechanical overlaps that have a universal form. The overlaps have a dramatic consequence: the microstates span a Hilbert space of log dimension equal to the Bekenstein-Hawking entropy. The semiclassical microstates we construct contain Einstein-Rosen bridges of arbitrary size behind their horizons. Our results imply that all these bridges can be interpreted as quantum superpositions of wormholes of size at most exponential in the entropy.

    hep-th 2026-07 accept novelty 7.0 of 10

    Shape and mass-density deformations of thin-shell AdS3 black holes and wormholes have stiffness kernels equal to two-point functions of defect-local displacement and mass-density operators, computed from linearized Li...

    hep-th 2026-07 conditional novelty 6.0 of 10

    Semiclassical pure AdS3 gravity states, labelled by fixed-area geodesic networks, are mapped to CFT2 primary states whose wavefunctions are networks of OPE coefficients.

  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.

  4. Resolving Black Hole Singularities in Jackiw-Teitelboim Gravity

    hep-th 2026-02 conditional novelty 6.0 of 10

    In JT gravity, the left confining potential required by spectral discreteness makes the wormhole length turn around and plateau, allowing boundary time to run past the would-be singularity and eliminating future horizons.

  5. Baby Universes from Thermal Pure States in SYK

    hep-th 2025-11 conditional novelty 6.0 of 10

    A JT-gravity baby universe is constructed with a microscopic dual given by a low-temperature thermal pure state of two coupled SYK models, and its bulk entanglement to the AdS region is O(N) below the phase transition.

  6. Microstate counting from defects in de Sitter

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

    hep-th 2025-11 conditional novelty 6.0 of 10

    A proposed universal finite entropy bound for quantum gravity is introduced and linked to the Gibbons-Hawking entropy of our universe, with BMN strings suggested as an unresolved test.

    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...

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

    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...

    hep-th 2025-05 conditional novelty 6.0 of 10

    The RT formula for entanglement in AdS3/CFT2, including phase transitions and multi-interval vacuum entropies, is derived from an assumed large-c ensemble of (B)CFT data, under the 'It from ETH' paradigm.

    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.
