We demonstrate that flux compactifications of type IIA string theory can classically stabilize all geometric moduli. For a particular orientifold background, we explicitly construct an infinite family of supersymmetric vacua with all moduli stabilized at arbitrarily large volume, weak coupling, and small negative cosmological constant. We obtain these solutions from both ten-dimensional and four-dimensional perspectives. For more general backgrounds, we study the equations for supersymmetric… Expand
Generalized flux vacua
We consider type II string theory compactified on a symmetric T6/2 orientifold. We study a general class of discrete deformations of the resulting four-dimensional supergravity theory, includingExpand
Fixing moduli in exact type IIA flux vacua.
Type IIA flux compactifications with O6-planes have been argued from a four dimensional effective theory point of view to admit stable, moduli free solutions. We discuss in detail the ten dimensionalExpand
Weakly-coupled IIA flux compactifications
We study compactifications of type IIA string theory on Calabi-Yau manifolds that are mirror to a subset of the type IIB LARGE-volume models. A combination of flux, α' corrections andExpand
Fluxes, moduli fixing and MSSM-like vacua in type IIA string theory
We review some of the features of Type IIA compactifications in the presence of fluxes. In particular, the case of T6/(Ω (-1) σ) orientifolds with RR, NS and metric fluxes is considered. This hasExpand
Low Energy Supersymmetry from Non-Geometry
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-geometricExpand
Runaway in the Landscape
We consider flux compactifications of type IIB string theory on the mirror of a rigid Calabi-Yau. In special cases, these models are dual to the type IIA flux vacua with runaway direction in fluxExpand
Enhanced symmetries in multiparameter flux vacua
We give a construction of type-IIB flux vacua with discrete R-symmetries and vanishing superpotential for hypersurfaces in weighted projective space with any number of moduli. We find that theExpand
Minimal Simple de Sitter Solutions
We show that the minimal set of necessary ingredients to construct explicit, four-dimensional de Sitter solutions from IIA string theory at tree level are O6-planes, nonzero Romans mass parameter,Expand

Exceptional flux compactifications
A bstractWe consider type II (non-)geometric flux backgrounds in the absence of brane sources, and construct their explicit embedding into maximal gauged D = 4 supergravity. This enables one toExpand


General N=1 supersymmetric flux vacua of massive type IIA string theory.
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. Expand
Moduli stabilization from magnetic fluxes in type I string theory
Abstract We show that type I string theory compactified in four dimensions in the presence of constant internal magnetic fields possesses N = 1 supersymmetric vacua, in which all Kahler class andExpand
Non-perturbative vacua for M-theory on G 2 manifolds
We study moduli stabilization in the context of M-theory on compact manifolds with G2 holonomy, using superpotentials from ∞ux and membrane instantons, and recent results for the Kahler potential ofExpand
Geometric constructions of nongeometric string theories
We advocate a framework for constructing perturbative closed string compactifications which do not have large-radius limits. The idea is to augment the class of vacua which can be described asExpand
Vacuum stability in heterotic M theory
The problem of the stabilization of moduli is discussed within the context of compactified strongly coupled heterotic string theory. It is shown that all geometric, vector bundle, and five-braneExpand
