de Sitter vacua from nonperturbative flux compactifications
Uppsala University, Disciplinary Domain of Science and Technology, Physics, Department of Physics and Astronomy, Theoretical Physics.

Abstract [en]

In this work we present stable de Sitter solutions of =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 approach that stabilises all moduli simultaneously in a de Sitter vacuum. By means of a genetic algorithm we find explicit solutions where different scales are separated and hierarchies are investigated.
