Flux compactifications, gauge algebras and De Sitter [PDF]
Physics Letters, Section B: Nuclear, Elementary Particle and High-Energy Physics, 2010 The introduction of (non-)geometric fluxes allows for N = 1 moduli stabilisation in a De Sitter vacuum. The aim of this Letter is to assess to what extent this is true in N = 4 compactifications.

DWSB in heterotic flux compactifications [PDF]
Journal of High Energy Physics, 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

Superpotentials from flux compactifications of M-theory [PDF]
, 2004 In flux compactifications of M-theory a superpotential is generated whose explicit form depends on the structure group of the 7-dimensional internal manifold. In this note, we discuss superpotentials for the structure groups: G_2, SU(3) or SU(2). For the

Flux Compactifications Grow Lumps [PDF]
Physical Review D, 2014 The simplest flux compactifications are highly symmetric—a q -form flux is wrapped uniformly around an extra-dimensional q -sphere. In this paper, we investigate solutions that break the internal SO ( q + 1 ) symmetry down to SO ( q ) × Z 2 ; we find a ...

Maximal temperature in flux compactifications [PDF]
Journal of Cosmology and Astroparticle Physics, 2005 Thermal corrections have an important effect on moduli stabilization leading to the existence of a maximal temperature, beyond which the compact dimensions decompactify. In this note, we discuss generality of our earlier analysis and apply it to the case

Embedding tensor of Scherk-Schwarz flux compactifications from eleven dimensions [PDF]
, 2014 We study the Scherk-Schwarz reduction of D = 11 supergravity with background fluxes in the context of a recently developed framework pertaining to D = 11 supergravity.

Flux compactifications in string theory: A comprehensive review [PDF]
, 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.

Metastable Vacua in Flux Compactifications and Their Phenomenology [PDF]
Journal of High Energy Physics, 2006 In the context of flux compactifications, metastable vacua with a small positive cosmological constant are obtained by combining a sector where supersymmetry is broken dynamically with the sector responsible for moduli stabilization, which is known as ...

Flavour mixings in flux compactifications [PDF]
Physical Review D, 2017 A multiplicity of quark-lepton families can naturally arise as zero-modes in flux compactifications. The flavour structure of quark and lepton mass matrices is then determined by the wave function profiles of the zero-modes. We consider a supersymmetric $
