On/off scale separation
read the original abstract
We discuss minimally supersymmetric AdS$_3$ flux vacua of massive type IIA supergravity on G2-orientifolds. We find that configurations that are scale-separated can be within finite distance from non scale-separated ones, while both remain at large volume, weak coupling and have moduli stabilization. The transition is achieved with the use of a D4-brane modulus, which allows the $F_4$ flux to jump, and has an effective potential always accessible to the three-dimensional low-energy theory. Our analysis further allows us to check the distance conjecture quantitatively, as we can track explicitly the masses of the KK modes.

Scale-separated vacua with extended supersymmetry
First examples of scale-separated vacua with extended supersymmetry are constructed as circle compactifications of 4D massive IIA solutions with additional fluxes and sources.

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

$G_2$ flux compactifications
Compactifications of the five 10D string theories on generic G2-structure 7-manifolds produce unified 3D N=1 effective theories with full scalar potentials, kinetic terms, and flux data organized via real superpotentials.

Broken and restored: a holographic constraint for AdS vacua with orbifolds
Holographic constraint on AdS vacua is violated for Z2 orbifolds but restored by non-abelian extensions, implying O-planes cannot wrap cycles in distinct homology classes.

Instabilities in scale-separated Casimir vacua

A note on the holographic consistency of DGKT-type vacua with $h^{2,1}=0$
Cancellations that satisfy a holographic three-point function constraint in DGKT vacua persist across examples with h^{2,1}=0 and more complicated triple-intersection numbers.
