Nongeometric Flux Compactifications [PDF]

JHEP0510:085,2005, 2005
We investigate a simple class of type II string compactifications which incorporate nongeometric "fluxes" in addition to "geometric flux" and the usual H-field and R-R fluxes. These compactifications are nongeometric analogues of the twisted torus.

Flux compactifications in string theory: a comprehensive review [PDF]

Phys.Rept. 423 (2006) 91-158, 2005
We present a pedagogical overview of flux compactifications in string theory, from the basic ideas to the most recent developments. We concentrate on closed string fluxes in type II theories. We start by reviewing the supersymmetric flux configurations with maximally symmetric four-dimensional spaces.

Supersymmetric M-theory compactifications with fluxes on seven-manifolds and G-structures [PDF]

JHEP 0307:004,2003, 2003
We consider Minkowski compactifications of M-theory on generic seven-dimensional manifolds. After analyzing the conditions on the four-form flux, we establish a set of relations between the components of the intrinsic torsion of the internal manifold and the components of the four-form flux needed for preserving supersymmetry.

Lectures on Nongeometric Flux Compactifications [PDF]

Class.Quant.Grav.24:S773-S794,2007, 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 superpotential which is invariant under T-duality.

Threshold corrections in heterotic flux compactifications [PDF]

Journal of High Energy Physics, 2017
We compute the one-loop threshold corrections to the gauge and gravitational couplings for a large class of N = 2 $$ \mathcal{N}=2 $$ non-Kähler heterotic compactifications with three-form flux, consisting in principal two-torus bundles over K3 surfaces.

Compactifying 5d superconformal field theories to 3d [PDF]

Journal of High Energy Physics, 2021
Building on recent progress in the study of compactifications of 6d (1, 0) superconformal field theories (SCFTs) on Riemann surfaces to 4d N $$ \mathcal{N} $$ = 1 theories, we initiate a systematic study of compactifications of 5d N $$ \mathcal{N} $$ = 1

Non-Kaehler attracting manifolds [PDF]

JHEP0604:001,2006, 2006
We observe that the new attractor mechanism describing IIB flux vacua for Calabi-Yau compactifications has a possible extension to the landscape of non-Kaehler vacua that emerge in heterotic compactifications with fluxes. We focus on the effective theories coming from compactifications on generalized half-flat manifolds, showing that the Minkowski ...

DWSB for heterotic flux compactifications [PDF]

Fortschr. Phys. 59, No. 7-8, 711-715 (2011), 2011
We investigate the construction of non-supersymmetric vacua in compactifications of heterotic string theory with intrinsic torsion and background fluxes. We do this by using the technique of domain-wall supersymmetry breaking (DWSB) that was developed in the context of type II compactifications.

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.
