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 ...

Dynamics of Warped Flux Compactifications [PDF]

Journal of High Energy Physics, 2008
We discuss the four dimensional effective action for type IIB flux compactifications, and obtain the quadratic terms taking warp effects into account.

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

Flux Compactifications on $(S_2)^N$ [PDF]

, 2014
We investigate a simple extra-dimensional model and its four-dimensional vacua. This model has a two-form flux and a positive cosmological constant, and the extra dimensions are compactified as the product of $N$ two-spheres. The theory is an interesting

Cosmological Perturbations in Flux Compactifications [PDF]

Journal of Cosmology and Astroparticle Physics, 2004
Kaluza-Klein compactifications with four-dimensional inflationary geometry combine the attractive idea of higher dimensional models with the attempt to incorporate four-dimensional early-time or late-time cosmology.

Flux Vacua Attractors and Generalized Compactifications

Journal of High Energy Physics, 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 ...

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.

Lectures on Nongeometric Flux Compactifications [PDF]

Classical and Quantum Gravity, 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 ...
