Automated consistent truncations and stability of flux compactifications
Journal of High Energy Physics, 2022 Classical flux compactifications contribute to a well-controlled corner of the string landscape, therefore providing an important testing ground for a variety of conjectures.

Maximal Temperature in Flux Compactifications [PDF]
, 2004 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

On mysteriously missing T-duals, H-flux and the T-duality group
, 2004 A general formula for the topology and H-flux of the T-duals of type II string theories with H-flux on toroidal compactifications is presented here.

Moduli identification methods in Type II compactifications
Journal of High Energy Physics, 2018 Recent work on four dimensional effective descriptions of the heterotic string has identified the moduli of such systems as being given by kernels of maps between ordinary Dolbeault cohomology groups.

Flux Vacua Attractors and Generalized Compactifications
, 2008 We investigate whether there are attractor equations for N=1 flux vacua in generalized compactifications. We fill a gap in the existing literature by verifying analytically that the recently proposed susy attractors, for type IIB CY(3) orientifold ...

Special points of inflation in flux compactifications
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 ...

Challenge for spontaneous CP violation in Type IIB orientifolds with fluxes [PDF]
Phys. Rev. D 102, 026004 (2020), 2020 We systematically investigate possibilities of realizing the spontaneous CP violation in Type IIB flux compactifications on toroidal orientifolds. Our detailed analysis leads to the presence of flat directions at degenerate CP-breaking and -conserving vacua for a generic choice of three-form fluxes, indicating that flux compactifications are not ...

On the flux vacua in F-theory compactifications
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.

A new de Sitter solution with a weakly warped deformed conifold
Journal of High Energy Physics, 2021 We revisit moduli stabilisation for type IIB flux compactifications that include a warped throat region corresponding to a warped deformed conifold, with an anti-D3-brane sitting at its tip.

Decay of flux vacua to nothing [PDF]
JCAP 1010:029,2010, 2010 We construct instanton solutions describing the decay of flux compactifications of a $6d$ gauge theory by generalizing the Kaluza-Klein bubble of nothing. The surface of the bubble is described by a smooth magnetically charged solitonic brane whose asymptotic flux is precisely that responsible for stabilizing the 4d compactification.
