abstract

We derive the 3D N=1 superpotential for the closed string sector of type IIB supergravity on toroidal O5 orientifolds with co-calibrated G2 structure and RR background flux. We find that such compactifications can provide full closed string moduli stabilization on supersymmetric AdS$_3$ vacua, and once we include brane-supersymmetry-breaking we also find indication for the existence of classical 3D de Sitter solutions. The latter however are rather difficult to reconcile with the shape moduli stabilization and flux quantization. We also discuss the possibility of achieving scale separation in AdS$_3$ and dS$_3$ vacua, but such effects seems to be hindered by the geometric flux quantization.

Discussion (0). Continue with ORCID to comment.

  1. Why 4D? Spontaneous Dimensional Selection from Gauge Criticality

    hep-ph 2026-07 conditional novelty 7.0 of 10

    Gauge criticality of Yang–Mills, via racetrack confinement and 3D dynamical SUSY breaking, can stabilize radii so that a macroscopic 4D spacetime emerges without being put in by hand.

  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. Warped G$_2$-throats in IIA and uplift dSillusions

    hep-th 2025-05 conditional novelty 6.0 of 10

    Anti-D2 brane uplifting of classical AdS3 vacua in IIA on G2 orientifolds is forbidden by O6 tadpole constraints, so dS3 must rely on quantum corrections to no-scale Minkowski vacua.

  4. 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.

  5. Warped G2 throats from deformed conifolds in IIA supergravity

    hep-th 2025-07 conditional novelty 5.0 of 10

    New non-singular IIA solutions with internal space (deformed conifold × S1)/Z2 provide warped G2 throats with finite 4-cycle or 3-cycle at the tip.
