We consider the one-loop partition function of free quantum field theory in locally Anti-de Sitter space-times. In three dimensions, the one loop determinants for scalar, gauge and graviton excitations are computed explicitly using heat kernel techniques. We obtain precisely the result anticipated by Brown and Henneaux: the partition function includes a sum over "boundary excitations" of AdS3, which are the Virasoro descendants of empty Anti-de Sitter space. This result also allows us to compute the one-loop corrections to the Euclidean action of the BTZ black hole as well its higher genus generalizations.

  1. A Tale of Two Hartle-Hawking Wave Functions: Fully Gravitational vs Partially Frozen

    hep-th 2026-05 unverdicted novelty 7.0

    In AdS the fully gravitational Hartle-Hawking wave function acquires a nontrivial one-loop phase while the partially frozen version stays real and positive; a partially frozen de Sitter sphere shows phase cancellation.

  2. M\"obius randomness in the Hartle-Hawking state

    hep-th 2025-05 unverdicted novelty 7.0

    The Hartle-Hawking state for toroidal quantum cosmologies is expressed in the Langlands decomposition as a sum over zeta zeros whose near-singularity dynamics follow the Hilbert-Pólya Hamiltonian and as a Möbius avera...

  3. Revisiting near-extremal and near-BPS black holes in AdS3 supergravity

    hep-th 2026-04 unverdicted novelty 6.0

    In AdS3 supergravity, the gravitational path integral at low temperatures in the near-horizon region is inequivalent to that of the BTZ background, with distinct contributions from bosonic fluctuations, Chern-Simons f...

  4. Spinning States and Unitarity in 3D Gravity

    hep-th 2026-04 unverdicted novelty 6.0

    Spinning states scaled with central charge cancel negative densities in 3D gravity, reinterpreted as bulk defects or overspinning BTZ quotients of AdS3 that preserve the gap but exhibit causal pathologies.

  5. Geometric realization of stress-tensor deformed field theory

    hep-th 2025-08 unverdicted novelty 6.0

    Stress-tensor deformations of QFTs are mapped to gravitational actions at metric saddles, with bidirectional examples and an induced Newton constant from the one-loop effective action of a massive scalar.

  6. AdS3 axion wormholes as stable contributions to the Euclidean gravitational path integral

    hep-th 2025-04 unverdicted novelty 6.0

    The paper shows that Euclidean axion wormholes remain regular and stable in AdS3 for any mouth radius to AdS radius ratio and across topologies, with computable actions that can be included in the 3D gravitational pat...

  7. Field Theory Models for a Holographic Superconductor in Two Dimensions

    hep-th 2026-05 unverdicted novelty 5.0

    Field theory models with Robin boundary conditions and modular invariance reproduce zero-winding holographic superconductor results in 2D CFTs and interpret fractional vortices via a Little-Parks toy model.

  8. From BTZ Perturbations to Schwarzian Modes: A Geometrical and Perturbative Analysis

    hep-th 2025-11 unverdicted novelty 5.0

    Schwarzian modes emerge from the general solution of BTZ perturbations at finite temperature with no rotational modes present, and are equivalently obtained via a Kerr-Schild construction that connects to the double copy.

  9. Lecture notes on strings in AdS$_3$ from the worldsheet and the AdS$_3$/CFT$_2$ duality

    hep-th 2026-01 unverdicted novelty 2.0

    Lecture notes deliver a self-contained pedagogical overview of worldsheet strings in AdS3 with NSNS flux, summarizing 25 years of results with emphasis on spectrally flowed correlation functions.
