“…We note that the masses squared above again give rise to dual conformal dimensions ∆ = {10, 8, 6, 2 or 1} that are all integers. This was previously noticed for nonsupersymmetric DGKT solutions in [49,51] and it would be interesting to extend the general analysis of [52] to non-supersymmetric AdS vacua.…”

We revisit flux compactifications of type IIB string theory on ‘spaces’ dual to rigid Calabi-Yau manifolds. This rather unexplored part of the string landscapes harbors many interesting four-dimensional solutions, namely supersymmetric $$ \mathcal{N} $$ N = 1 Minkowski vacua without flat direction and infinite families of AdS vacua, some potentially with unrestricted rank for the gauge group. We also comment on the existence of metastable dS solutions in this setup. We discuss how these solutions fit into the web of swampland conjectures.

“…With regards to the constructions in [4], which are classical, one could suspect that the inconsistent approximation is the use of "smeared" orientifold sources. In the meantime, various difficulties for achieving scale separation in Type II are discussed in [12][13][14], further recent developments can be found in [15][16][17][18][19], and implications on the holographic side are discussed in [20][21][22].…”

We evaluate the backreaction of O6-planes in scale-separated AdS3 flux vacua of massive Type IIA. Using the appropriate flux scaling we show that the corrections to the various background fields and moduli are controlled and subleading when going from smeared to localized sources. Similarly, the backreaction corrections to the scalar potential are parametrically small in the scale-separation limit, assuming always that the near-O6-plane singularities will find a resolution within string theory, even in the presence of a Romans mass. Our analysis is based on the equations of motion and therefore applies also to the non-supersymmetric vacua.

“…All of these branches contain an infinite number of vacua that is generated by a rescaling of internal fluxes, as in the supersymmetric case, and along which parametric scale separation is achieved. Remarkably, the mass spectrum found in [16] for some of these branches has an amusing holographic interpretation [17,18], while the remaining branches do not present this feature [19].…”

We consider massive type IIA orientifold compactifications of the form AdS 4 × X 6 , where X 6 admits a Calabi-Yau metric and is threaded by background fluxes. From a 4d viewpoint, fluxes generate a potential whose vacua have been classified, including one N = 1 and three perturbatively stable N = 0 branches. We reproduce this result from a 10d viewpoint, by solving the type IIA equations at the same level of accuracy as previously done for the N = 1 branch. All solutions exhibit localised sources and parametric scale separation. We then analyse the non-perturbative stability of the N = 0 branches. We consider new 4d membranes, obtained from wrapping D8-branes on X 6 or D6-branes on its divisors, threaded by non-diluted worldvolume fluxes. Using them we show that all branches are compatible with the Weak Gravity Conjecture for membranes. In fact, most vacua satisfy the sharpened conjecture that predicts superextremal membranes in N = 0 settings, except for a subset whose non-perturbative stability remains an open problem.
