Taxonomy of type II orientifold flux vacua in 3D
Álvaro Arboleya, Gabriele Casagrande, Adolfo Guarino +1
We complete the study initiated in \cite{Arboleya:2024vnp} and investigate three-dimensional (3D) flux vacua of type II orientifold reductions on twisted tori that include a single…
Open strings in type IIB AdS flux vacua
Álvaro Arboleya, Adolfo Guarino, Matteo Morittu +1
The role of open strings is investigated in the context of AdS flux vacua arising from type IIB orientifold reductions. On the one hand, contrary to expectations, the perturb…
On type IIB AdS flux vacua with scale separation and integer conformal dimensions
Álvaro Arboleya, Adolfo Guarino, Matteo Morittu
We review recent progress in constructing type IIB AdS flux vacua that exhibit parametrically-controlled scale separation and come along with integer-valued conformal dimensi…
Type II orientifold flux vacua in 3D
Álvaro Arboleya, Adolfo Guarino, Matteo Morittu
We initiate a systematic study of type II orientifold flux vacua in three dimensions including gauge and metric fluxes, O-planes and D-branes. We derive simple flux models (we dub…
Scale-separated AdSS vacua from IIA orientifolds
Fotis Farakos, Matteo Morittu
We study supersymmetric AdS flux vacua of massive type-IIA supergravity on anisotropic G2 orientifolds. Depending on the value of the flux the seven-dimensional compact s…
On/off scale separation
Fotis Farakos, Matteo Morittu, George Tringas
We discuss minimally supersymmetric AdS flux vacua of massive type IIA supergravity on G2-orientifolds. We find that configurations that are scale-separated can be within finit…
Goldstino condensation at large N
Fotis Farakos, Matteo Morittu
We analyze the standard fermionic 4D Volkov-Akulov action with N global non-linear supersymmetries. We find that the stationary points of the system are described by an effective p…
Anti-brane uplift instability from goldstino condensation
Gianguido Dall'Agata, Maxim Emelin, Fotis Farakos +1
We investigate the possible appearance of composite states of the goldstino in models with four-dimensional non-linear supersymmetry and we provide a description of their dynamics…
The unbearable lightness of charged gravitini
Gianguido Dall'Agata, Maxim Emelin, Fotis Farakos +1
We prove that charged gravitini cannot have parametrically small or vanishing Lagrangian mass in de Sitter vacua of extended supergravity while respecting the magnetic weak gravity…
Covariant formulation of BPS black holes and the scalar weak gravity conjecture
Gianguido Dall'Agata, Matteo Morittu
In this note we analyze the BPS black hole equations in extended supergravities and we find two interesting relations involving first and second derivatives of combinations of the…
