Maximal supergravity from IIB flux compactifications [PDF]
Physics Letters B, 2004 Using a recently proposed group-theoretical approach, we explore novel gaugings of maximal supergravity in four dimensions with gauge group embeddings that can be generated by fluxes of IIB string theory. The corresponding potentials are positive without

Lectures on nongeometric flux compactifications [PDF]
Classical and Quantum Gravity, 2007 These notes present a pedagogical review of nongeometric flux compactifications. We begin by reviewing well-known geometric flux compactifications in Type II string theory, and argue that one must include nongeometric "fluxes" in order to have a ...

A worldsheet description of flux compactifications [PDF]
Journal of High Energy PhysicsWe demonstrate how recent developments in string field theory provide a framework to systematically study type II flux compactifications with non-trivial Ramond-Ramond profiles.

Resolving spacetime singularities in flux compactifications & KKLT [PDF]
Journal of High Energy Physics, 2021 In flux compactifications of type IIB string theory with D3 and seven-branes, the negative induced D3 charge localized on seven-branes leads to an apparently pathological profile of the metric sufficiently close to the source.

Flux vacua attractors and generalized compactifications [PDF]
Journal of High Energy Physics, 2009 We investigate whether there are attractor equations for N=1 flux vacua in generalized compactifications. We fill a gap in the existing literature by verifying analytically that the recently proposed susy attractors, for type IIB CY(3) orientifold ...

Flux compactifications on
, 2014 We investigate a simple extra-dimensional model and its four-dimensional vacua. This model has a two-form flux and a positive cosmological constant, and the extra dimensions are compactified as the product of $N$ two-spheres. The theory is an interesting

DWSB in heterotic flux compactifications [PDF]
, 2010 We address the construction of non-supersymmetric vacua in heterotic compactifications with intrinsic torsion and background fluxes. In particular, we implement the approach of domain-wall supersymmetry breaking (DWSB) previously developed in the context

D-branes on AdS flux compactifications [PDF]
, 2008 We study D-branes in N=1 flux compactifications to AdS_4. We derive their supersymmetry conditions and express them in terms of background generalized calibrations.

Moduli Potentials in Type IIA Compactifications with RR and NS Flux [PDF]
, 2004 We describe a simple class of type IIA string compactifications on Calabi-Yau manifolds where background fluxes generate a potential for the complex structure moduli, the dilaton, and the K\"ahler moduli.

Automated consistent truncations and stability of flux compactifications
Journal of High Energy Physics, 2022 Classical flux compactifications contribute to a well-controlled corner of the string landscape, therefore providing an important testing ground for a variety of conjectures.
