TL;DR
This paper explores the landscape of vacua in type IIA flux compactifications with extended supersymmetry, revealing a unique theory with stable, non-supersymmetric minima and discussing their uplift to maximal supergravity.
Contribution
It provides a comprehensive analysis of isotropic vacua in N=4 gauged supergravities from type IIA compactifications, including their uplift to N=8 supergravity and stability properties.
Findings
Identification of a unique theory of vacua

Abstract
We analyse geometric type IIA flux compactifications leading to N=4 gauged supergravities in four dimensions. The complete landscape of isotropic vacua is presented, which turns out to belong to a unique theory. The solutions admit an uplift to maximal supergravity due to the vanishing of the flux-induced tadpoles for all the supersymmetry-breaking branes. Such an uplift is sketched out and the full N=8 mass spectra are discussed. We find the interesting presence of a non-supersymmetric and nevertheless stable minimum.
