On scale-separated supersymmetric AdS flux vacua
N. Cribiori, F. Farakos, N. Liatsos
We argue that scale-separated AdS vacua with at least two preserved supercharges cannot arise from flux compactifications in a regime of computational control. We deduce this b…

Supergravity with Local Scaling Symmetry in Four Dimensions
Nikolaos Liatsos
We construct the most general four-dimensional supergravity coupled to an arbitrary number of vector multiplets in which the global scaling symmetry is gauged, in…

On Global Symmetries and Fayet-Iliopoulos Terms
Fotis Farakos, Alex Kehagias, Nikolaos Liatsos
We revisit the genuine Fayet-Iliopoulos terms of 4D N=1 supergravity. Such terms are commonly believed to preserve a global symmetry, and therefore they are in conflict with the pr…
