Type-IIA flux compactifications and N=4 gauged supergravities
- Mathematics
- 2009
We establish the precise correspondence between Type-IIA flux compactifications preserving an exact or spontaneously broken = 4 supersymmetry in four dimensions, and gaugings of their effective = 4…
6D (1,1) gauged supergravities from orientifold compactifications
- MathematicsJournal of High Energy Physics
- 2020
We study dimensional reductions of M-theory/type II strings down to 6D in the presence of fluxes and spacetime filling branes and orientifold planes of different types. We classify all inequivalent…
Lobotomy of flux compactifications

A bstractWe provide the dictionary between four-dimensional gauged supergravity and type II compactifications on $ \mathbb{T} $6 with metric and gauge fluxes in the absence of supersymmetry breaking…
Lobotomy of ux compactications

We provide the dictionary between four-dimensional gauged supergravity and type II compactications on T 6 with metric and gauge uxes in the absence of supersym- metry breaking sources, such as branes…
Low Energy Supersymmetry from Non-Geometry
- Physics
- 2007
We study a class of flux compactifications that have all the moduli stabilised, a high (GUT) string scale and a low (TeV) gravitino mass that is generated dynamically. These non-geometric…
On general flux backgrounds with localized sources
- Physics
- 2007
We derive new consistency conditions for string compactifications with generic fluxes (RR, NSNS, geometrical) and localized sources (D-branes, NS-branes, KK-monopoles). The constraints are all…
Exploring double field theory
- Physics
- 2013
A bstractWe consider a flux formulation of Double Field Theory in which fluxes are dynamical and field-dependent. Gauge consistency imposes a set of quadratic constraints on the dynamical fluxes,…
KK-monopoles and G-structures in M-theory/type IIA reductions
- Geology
- 2014
A bstractWe argue that M-theory/massive IIA backgrounds including KK-monopoles are suitably described in the language of G-structures and their intrinsic torsion. To this end, we study classes of…
Simple de Sitter solutions

- 2008
We present a framework for de Sitter model building in type IIA string theory, illustrated with specific examples. We find metastable dS minima of the potential for moduli obtained from a…

The O(dd) story of massive supergravity
- Physics
- 1999
The low energy effective action describing the standard Kaluza-Klein reduction of heterotic string theory on a d-torus possesses a manifest O(d,d+16) symmetry. We consider generalized Scherk-Schwarz…
New supersymmetric string compactifications
- Mathematics, Physics
- 2003
We describe a new class of supersymmetric string compactifications to 4d Minkowski space. These solutions involve type II strings propagating on (orientifolds of) non Calabi-Yau spaces in the…
Gauging of Flat Groups in Four Dimensional Supergravity
- Physics, Mathematics
- 2002
We show that N = 8 spontaneously broken supergravity in four dimensions obtained by Scherk-Schwarz generalized dimensional reduction can be obtained from a pure four dimensional perspective by…
Hierarchies from fluxes in string compactifications
- Mathematics
- 2002
Warped compactifications with significant warping provide one of the few known mechanisms for naturally generating large hierarchies of physical scales. We demonstrate that this mechanism is…
D terms from D-branes, gauge invariance and moduli stabilization in flux compactifications
- Mathematics
- 2006
We elucidate the structure of D terms in = 1 orientifold compactifications with fluxes. As a case study, we consider a simple orbifold of the type-IIA theory with D6-branes at angles, O6-planes and…
More Dual Fluxes and Moduli Fixing
- Mathematics
- 2006
We generalize the recent proposal that invariance under T-duality leads to additional non-geometric fluxes required so that superpotentials in type IIA and type IIB orientifolds match. We show that…
