On the cosmology of type IIA compactifications on SU(3)-structure manifolds
- Mathematics
- 2009
We study cosmological properties of type IIA compactifications on orientifolds of SU(3)-structure manifolds with non-vanishing geometric flux. These compactifications give rise to effective 4D = 1…
Supersymmetric sources, integrability and generalized-structure compactifications
- Mathematics
- 2007
In the context of supersymmetric compactifications of type II supergravity to four dimensions, we show that orientifold sources can be compatible with a generalized SU(3) × SU(3)-structure that is…
General N=1 supersymmetric flux vacua of massive type IIA string theory.
- PhysicsPhysical review letters
- 2005
It is shown that such flux vacua exist when the internal geometry is nearly Kähler, and the four-dimensional cosmological constant, while negative, becomes small in the vacuum with the weak string coupling.
Building MSSM flux vacua
- Physics
- 2004
We construct N=1 and N=0 chiral four-dimensional vacua of flux compactification in Type IIB string theory. These vacua have the common features that they are free of tadpole instabilities (both NSNS…
A new family of non-homogeneous type IIA flux vacua from AdS4/CFT3
- Mathematics
- 2009
In arXiv:0901.0969 a set of three-dimensional Chern-Simons-matter theories with different amounts of global symmetry and supersymmetry is introduced, which deform the ABJM construction to include…
Moduli stabilization and cosmology of type IIB on SU(2)-structure orientifolds
- Mathematics
- 2009
We consider type IIB flux compactifications on six-dimensional SU(2)-structure manifolds with O5- and O7-planes. These six-dimensional spaces allow not only for F3 and H3 fluxes but also for F1 and…
Generalized non-supersymmetric flux vacua
- Mathematics
- 2008
We discuss a novel strategy to construct 4D = 0 stable flux vacua of type II string theory, based on the existence of BPS bounds for probe D-branes in some of these backgrounds. In particular, we…
A second look at = 1 supersymmetric AdS4 vacua of type IIA supergravity
- Mathematics
- 2007
We show that a class of type IIA vacua recently found within the D=4 effec- tive approach corresponds to compactification on AdS 4 ×S 3 ×S 3 /Z 3 . The results obtained using the effective method…

Type IIB solutions with interpolating supersymmetries
- Mathematics

We study type IIB supergravity solutions with four supersymmetries that interpolate between two types widely considered in the literature: the dual of Becker and Becker's compactifications of…

New formulations of D = 10 supersymmetry and D8-O8 domain walls
- Physics
- 2001
We discuss a generalized form of IIA/IIB supergravity depending on all R-R potentials C-(p) (p = 0, 1,..., 9) as the effective field theory of type IIA/IIB superstring theory. For the IIA case we…
Notes on SU(3) structures in type IIB supergravity
- Physics

We study solutions of type IIB supergravity with an SU(3) structure group and four dimensional Poincare invariance and present relations among the bosonic fields which follow from the supersymmetry…
D=4 chiral string compactifications from intersecting branes
- Physics
- 2000
Intersecting Dp-branes often give rise to chiral fermions living on their intersections. We study the construction of four-dimensional chiral gauge theories by considering configurations of type II…

We analyse the geometrical structure of supersymmetric solutions of type II supergravity of the form 1,9−n×Mn with non-trivial NS flux and dilaton. Solutions of this type arise naturally as the…
