Contribution

It introduces a supergravity analysis approach using generalized geometry to study non-geometric compactifications, finding new Minkowski vacua with all moduli stabilized.

Findings

Existence of supersymmetric Minkowski vacua with all moduli stabilized.

Moduli values can be parametrically controlled and arbitrarily large.

All tadpole conditions are satisfied in these vacua.

Abstract

We study the vacuum structure of compactifications of type II string theories on orientifolds with SU(3)xSU(3) structure. We argue that generalised geometry enables us to treat these non-geometric compactifications using a supergravity analysis in a way very similar to geometric compactifications. We find supersymmetric Minkowski vacua with all the moduli stabilised at weak string coupling and all the tadpole conditions satisfied. Generically the value of the moduli fields in the vacuum is parametrically controlled and can be taken to arbitrarily large values.
