abstract

We study supersymmetric AdS$_3$ flux vacua of massive type-IIA supergravity on anisotropic G2 orientifolds. Depending on the value of the $F_4$ flux the seven-dimensional compact space can either have six small and one large dimension such that the external space is scale-separated and effectively four-dimensional, or all seven compact dimensions small and parametrically scale-separated from the three external ones. Within this setup we also discuss the Distance Conjecture (including appropriate D4-branes), and highlight that such vacua provide a non-trivial example of the so-called Strong Spin-2 Conjecture.

  1. 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.

  2. On the branes behind scale-separated AdS$_{3}$ flux vacua

    hep-th 2026-06 conditional novelty 6.5 of 10

    Scale-separated supersymmetric AdS3 flux vacua of type IIB G2-orientifolds arise as the near-horizon region of codimension-one smeared D1-D5-KK5 intersections.

  3. Integer dual dimensions in scale-separated AdS$_3$ from massive IIA

    hep-th 2025-02 conditional novelty 6.0 of 10

    Massive IIA flux compactifications on singular and Joyce G2 orbifolds yield scale-separated AdS3 vacua whose dual operator dimensions are integer up to parametrically small corrections.
