Scale-separated vacua with extended supersymmetry
Niccolò Cribiori, Fotis Farakos, Alexandros Zarafonitis
We propose the first examples of scale-separated vacua with extended supersymmetry. They arise as circle compactifications of four-dimensional vacua of massive type IIA supergravit…
Super Yang-Mills with partially non-linear extended supersymmetry
Fotis Farakos, Ulf Lindström
We discuss 4D N=2 non-abelian gauge theories where one supersymmetry is preserved while the other one is spontaneously broken and non-linearly realized. The goldstino resides in a…
Warped G2 throats from deformed conifolds in IIA supergravity
Fotis Farakos
We analyze the IIA supergravity solutions corresponding to a warped product of a 3D external Minkowski space and a 7D internal non-compact space, with the latter being the direct p…
Warped G-throats in IIA and uplift dSillusions
Fotis Farakos, George Tringas, Thomas Van Riet
Flux compactifications of IIA supergravity on orientifolded G-manifolds have been argued to allow for classical Minkowski vacua with moduli and scale-separated AdS vacu…
Integer dual dimensions in scale-separated AdS from massive IIA
Fotis Farakos, George Tringas
We study supersymmetric scale-separated AdS flux vacua of massive IIA on G2 orbifolds with smeared orientifold planes. We consider two types of orbifolds which, wit…
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…
Non-Linear Supergravity and Inflationary Cosmology
Ignatios Antoniadis, Emilian Dudas, Fotis Farakos +1
We review a series of developments concerning non-linear realizations of supersymmetry coupled to supergravity, with emphasis on some applications to inflationary Cosmology.
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…
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…
Is Gauge Mediation in the Swampland?
Ioannis Dalianis, Fotis Farakos, Alex Kehagias
We note that the typical gauge mediation of supersymmetry breaking is in tension with the global limit of the festina lente swampland bound. The alternatives are mediation/breaking…
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…
Supergravity EFTs and swampland constraints
Niccolò Cribiori, Fotis Farakos
In these proceedings, we review recent progress in analyzing the behavior of lower-dimensional supergravity theories when combined with swampland conjectures. We show that within s…
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…
O6-plane backreaction on scale-separated Type IIA AdS vacua
Maxim Emelin, Fotis Farakos, George Tringas
We evaluate the backreaction of O6-planes in scale-separated flux vacua of massive Type IIA. Using the appropriate flux scaling we show that the corrections to the v…
Complex Linear Multiplets and Local Supersymmetry Breaking
Fotis Farakos, Alex Kehagias, Nikolaos Liatsos
We study supersymmetry breaking from a complex linear superfield coupled to 4D N=1 supergravity. The theory has two classically decoupled vacua, one supersymmetric and one with bro…
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…
Three-dimensional flux vacua from IIB on co-calibrated G2 orientifolds
Maxim Emelin, Fotis Farakos, George Tringas
We derive the 3D N=1 superpotential for the closed string sector of type IIB supergravity on toroidal O5 orientifolds with co-calibrated G2 structure and RR background flux. We fin…
On the F-term problem and quintessence supersymmetry breaking
Fotis Farakos
Inspired by the stringy quintessence F-term problem we highlight a generic contribution to the effective moduli masses that arises due to kinetic mixings between the moduli and the…
de Sitter decay through goldstino evaporation
Fotis Farakos, Alex Kehagias, Nikolaos Liatsos
We study supergravity theories with supersymmetry intrinsically non-linearly realized supported only by four-form flux. We demonstrate that supersymmetry can be restored by the eva…
Classical de Sitter solutions in three dimensions without tachyons?
Fotis Farakos, George Tringas, Thomas Van Riet
We continue the study of compactifications of massive IIA supergravity on G2 orientifolds and demonstrate that breaking supersymmetry with anti-D2 and anti-D6 sources leads to 3d t…
No-scale and scale-separated flux vacua from IIA on G2 orientifolds
Fotis Farakos, George Tringas, Thomas Van Riet
We discuss flux compactifications of IIA string theory on G2 holonomy spaces with O2/O6-planes to three dimensions and find two classes of solutions: 1) No-scale Minkowski vacua fr…
Quintessence from higher curvature supergravity
Fotis Farakos
In this contribution we revisit higher curvature N=1 supergravity and discuss the quintessence phase that can appear due to the terms. In particular we focus on the bosonic s…
Three-forms and Fayet-Iliopoulos terms in Supergravity: Scanning Planck mass and BPS domain walls
Niccolò Cribiori, Fotis Farakos, George Tringas
We embed a new three-form vector multiplet in supergravity and we show that it can be used to generate dynamically the Hilbert--Einstein term. We then recast the theor…
