Weakly Coupled de Sitter Vacua with Fluxes and the Swampland

, 2019
It was recently argued that the swampland distance conjecture rules out dS vacua at parametrically large field distances. We point out that this conclusion can in principle be avoided in the presence of large fluxes that are not bounded by a tadpole ...

PP-Waves, M-Theory and Fluxes

, 2003
We study a new type of warped compactifications of M-theory on eight manifolds for which nowhere vanishing covariantly constant spinors of indefinite chirality on the internal manifold can be found.

M-theory Compactifications to Three Dimensions with M2-brane Potentials [PDF]

, 2013
We study a class of compactifications of M-theory to three dimensions that preserve N=2 supersymmetry and which have the defining feature that a probe space-time filling M2 brane feels a non-trivial potential on the internal manifold.

Consistent truncation and de Sitter space from gravitational instantons

Journal of High Energy Physics, 2019
We construct a four-dimensional consistent truncation to the bosonic part of the universal sector of Calabi-Yau IIA compactification (i.e. the gravity multiplet, one vectormultiplet, and one hypermultiplet) in the presence of background flux and ...

Building MSSM Flux Vacua

, 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 and RR) even for models with N=0 supersymmetry.

Hypermoduli Stabilization, Flux Attractors, and Generating Functions [PDF]

, 2010
We study stabilization of hypermoduli with emphasis on the effects of generalized fluxes. We find a class of no-scale vacua described by ISD conditions even in the presence of geometric flux. The associated flux attractor equations can be integrated by a

Calabi-Yau period geometry and restricted moduli in Type II compactifications

Journal of High Energy Physics
The period geometry of Calabi-Yau n-folds — characterised by their variations of Hodge structure governed by Griffiths transversality, a graded Frobenius algebra, an integral monodromy and an intriguing arithmetic structure — is analysed for applications
