Flux compactifications and naturalness [PDF]
Journal of High Energy Physics, 2018 Free massless scalars have a shift symmetry. This is usually broken by gauge and Yukawa interactions, such that quantum corrections induce a quadratically divergent mass term.

Lobotomy of Flux Compactifications [PDF]
Journal of High Energy Physics, 2014 We provide the dictionary between four-dimensional gauged supergravity and type II compactifications on T6 with metric and gauge fluxes in the absence of supersymmetry breaking sources, such as branes and orientifold planes. Secondly, we prove that there

Three-forms in supergravity and flux compactifications [PDF]
European Physical Journal C: Particles and Fields, 2017 We present a duality procedure that relates conventional four-dimensional matter-coupled $$\mathcal{N}=1$$ N = 1 supergravities to dual formulations in which auxiliary fields are replaced by field strengths of gauge three-forms.

Nongeometric flux compactifications [PDF]
Journal of High Energy Physics, 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.

M-theory and type IIA flux compactifications
Journal of High Energy Physics, 2012 We consider compactifications of M-theory and type IIA string theory to four dimensions. For Minkowski space-time, a supergravity no-go theorem forbids flux supported in the internal space.

Special points of inflation in flux compactifications [PDF]
Nuclear Physics B, 2015 We study the realization of axion inflation models in the complex structure moduli spaces of Calabi–Yau threefolds and fourfolds. The axions arise close to special points of these moduli spaces that admit discrete monodromy symmetries of infinite order ...

Computing brane and flux superpotentials in F-theory compactifications [PDF]
Journal of High Energy Physics, 2010 In four-dimensional F-theory compactifications with N=1 supersymmetry the fields describing the dynamics of space-time filling 7-branes are part of the complex structure moduli space of the internal Calabi-Yau fourfold.

On the flux vacua in F-theory compactifications [PDF]
Physics Letters B, 2017 We study moduli stabilization of the F-theory compactified on an elliptically fibered Calabi–Yau fourfold. Our setup is based on the mirror symmetry framework including brane deformations.

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.

Warping the Kähler potential of F-theory/IIB flux compactifications [PDF]
Journal of High Energy Physics, 2015 We identify the low-energy Kähler potential of warped F-theory/IIB flux compactifications whose light spectrum includes universal, Kähler, axionic and mobile D3-brane moduli.
