abstract

We discuss the properties of massive type IIA flux compactifications. In particular, we investigate in which case one can obtain dS vacua at large volume and small coupling. We support a general discussion of scaling symmetries with the analysis of a concrete example. We find that the large volume and weak coupling limit requires a large number of O6-planes. Since these are bound for any given compactification space one cannot get arbitrarily good control over $\alpha'$ and string loop corrections.

Discussion (0). Continue with ORCID to comment.

  1. 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.

  2. Pure D-brane Black Holes: BPS Counting and non-BPS Vacua

    hep-th 2026-01 conditional novelty 5.0 of 10

    The (1,1,1,5) and (1,1,1,6) D2-D2-D2-D6 BPS systems yield 2032 and 5616 vacua, matching U-duality, while the analogous non-BPS system has no zero-energy vacua and six doubly-degenerate low-energy minima.

  3. Dark energy from string theory: an introductory review

    hep-th 2026-03 unverdicted novelty 2.0 of 10

    String theory imposes constraints on dark energy but permits various construction attempts for de Sitter vacua and single-field exponential quintessence models despite obstructions.
