De Sitter Vacua from Non-perturbative Flux Compactifications

preprint2014arXivOpen access

Abstract

We present stable de Sitter solutions of N=1\mathcal{N} = 1 supergravity in a geometric type IIB duality frame with the addition of non-perturbative contributions. Contrary to the standard approach, we retain the moduli dependence of both the tree level superpotential and its non-perturbative contribution. This provides the possibility for a single-step stabilisation of all moduli simultaneously in a de Sitter vacuum. Using a genetic algorithm we find explicit solutions with different features.
