M-theory compactification, fluxes and AdS_4

open access: yes, 2004
We analyze supersymmetric solutions of M-theory based an a seven-dimensional internal space with SU(3) structure and a four-dimensional maximally symmetric space. The most general supersymmetry conditions are derived and we show that a non-vanishing cosmological constant requires the norms of the two internal spinors to differ.

Maximal temperature in flux compactifications

open access: yes, 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

Heterotic compactifications with flux

open access: yes, 2017
We study various aspects of heterotic compactifications with torsion. We de- fine and compute the dressed elliptic genus associated to Fu-Yau compactifications, and use this result to compute one-loop threshold corrections to various BPS-saturated cou ...

Flux Compactifications and Intersecting Sources

open access: yes
When discussing the expansion of the universe, we often use a scalarpotential as a model. To build this type of model, one can use flux compactifications in type IIB string theory.

Axion stabilization in type IIB flux compactifications [PDF]

open access: yes, 2009
A scenario for stabilization of axionic moduli fields in the context of type IIB Calabi-Yau flux compactifications is discussed in detail. We consider the case of a Calabi-Yau orientifold with h1,1−≠0 which allows for the presence of B2 and C2-moduli. In
