TL;DR

This paper uses a group-theoretical approach to connect IIB string theory flux compactifications with novel gaugings in four-dimensional maximal supergravity, revealing potentials without stationary points and domain wall solutions.

Contribution

It introduces a new method to generate gaugings of maximal supergravity from IIB fluxes, expanding understanding of flux compactifications and their supergravity counterparts.

Findings

Potentials are positive with no stationary points.

Some solutions admit domain walls liftable to ten dimensions.

Truncations describe type-IIB flux compactifications on T^6 orientifolds.

Abstract

Using a recently proposed group-theoretical approach, we explore novel gaugings of maximal supergravity in four dimensions with gauge group embeddings that can be generated by fluxes of IIB string theory. The corresponding potentials are positive without stationary points. Some allow domain wall solutions which can be elevated to ten dimensions. Appropriate truncations describe type-IIB flux compactifications on T^6 orientifolds leading to non-maximal, four-dimensional, supergravities.
