Abstract
Moduli stabilization is key to obtaining phenomenologically viable string models. Nongeometric compactifications, like T-duality orbifolds (T folds), are capable of freezing many moduli. However, in this paper we emphasize that T folds, admitting free fermionic descriptions, can be associated with a large number of different T folds with varying number of moduli, since the fermion pairings for bosonization are far from unique. Consequently, in one description a fermionic construction might appear to be asymmetric, and hence nongeometric, while in another it admits a symmetric orbifold description. We introduce the notion of intrinsically asymmetric T folds for fermionic constructions that do not admit any symmetric orbifold description after bosonization. Finally, we argue that fermion symmetries induce mappings in the bosonized description that extend the T-duality group.
