In this paper we study the relation between six-dimensional supergravity compactified on S^3 X AdS_3 and certain two-dimensional conformal field theories. We compute the Kaluza-Klein spectrum of supergravity using representation theory; these methods are quite general and can also be applied to other compactifications involving anti-de Sitter spaces. A detailed comparison between the spectrum of the two-dimensional conformal field theory and supergravity is made, and we find complete agreement. This applies even at the level of certain non-chiral primaries, and we propose a resolution to the puzzle of the missing states recently raised by Vafa. As a further illustration of the method the Kaluza-Klein spectra of F-theory on M^6 X S^3 X AdS_3 and of M-theory on M^6 X S^2 X AdS_3 are computed, with M^6 some Calabi-Yau manifold.

  1. The Resolved Elliptic Genus and the D1-D5 CFT

    hep-th 2026-03 unverdicted novelty 8.0 of 10

    The resolved elliptic genus refines the supersymmetry index for the D1-D5 CFT by summing only over symmetry sectors that mix under a deformed supercharge, yielding agreement with supergravity below the black-hole thre...

  2. Asymptotic T-duality in three dimensions

    hep-th 2024-12 conditional novelty 8.0 of 10

    By applying Buscher T-duality rules asymptotically to Brown-Henneaux boundary conditions, the authors construct a phase space for three-dimensional black strings whose asymptotic symmetry algebra contains bms2, bms3, ...

  3. Circular strings, magnons, plane waves and local quenches in BTZ

    hep-th 2026-02 unverdicted novelty 7.0 of 10

    A coordinate map from AdS3 to BTZ allows construction of circular strings, magnons, and plane waves whose SL(2,R) charges are related by a boost, dual to asymmetric local quenches in the thermal CFT.

  4. Scale separation on AdS$_3\times S^3$ with and without supersymmetry

    hep-th 2025-04 conditional novelty 7.0 of 10

    The complete Kaluza-Klein spectrum of six-dimensional Salam-Sezgin supergravity on AdS3 times a squashed three-sphere is computed; in the large-squashing limit, all but a small set of low-energy fields acquire infinite mass.

  5. Demystifying the Massless Sector in AdS_3 Quantum Spectral Curve

    hep-th 2024-12 conditional novelty 7.0 of 10

    Massless modes in the AdS3 x S3 x T4 quantum spectral curve are shown to emerge as zeros on the branch cut, yielding Bethe equations and uniquely constrained dressing phases.

  6. Wilson loop in AdS$_3 \times S^3 \times T^4$ from quantum M2 brane

    hep-th 2026-03 unverdicted novelty 6.0 of 10

    The 1-loop M2-brane partition function for the Wilson loop in AdS3 x S3 x T4 equals kappa over sqrt(2 pi) with no higher-genus string corrections.

  7. Non-supersymmetric strings on AdS$_3$: a world-sheet perspective

    hep-th 2025-12 conditional novelty 6.0 of 10

    On AdS3×S3×S3×S1, a Wilson-line deformation of the Spin(16)×Spin(16)⋊Z2 heterotic string produces a level-matched tachyon, so the classical moduli space contains unstable regions.

  8. Instability of Black Holes in AdS$_3 \times S^3$

    hep-th 2025-07 conditional novelty 6.0 of 10

    Near-extremal AdS3 x S3 black holes are thermodynamically and dynamically unstable, decaying to a central black hole plus chiral primaries or new macroscopic giant strings.

  9. Semiclassical quantization of M5 brane probes wrapped on $\textrm{AdS}_3\times S^3$ and defect anomalies

    hep-th 2024-11 conditional novelty 6.0 of 10

    One-loop free energies of the three AdS3 x S3 M5 brane probes vanish, confirming the absence of order N^0 terms in the defect b-anomaly coefficients.
