We study, by means of mirror symmetry, the quantum geometry of the Kähler-class parameters of a number of Calabi–Yau manifolds that have b11 = 2. Our main interest lies in the structure of the moduli… (More)

We generalize the recent proposal that invariance under T-duality leads to additional nongeometric fluxes required so that superpotentials in type IIA and type IIB orientifolds match. We show that… (More)

We study the effects of adding RR, NS and metric fluxes on a T/(Ω(−1)LI3) Type IIA orientifold. By using the effective flux-induced superpotential we obtain Minkowski or AdS vacua with broken or… (More)

We discuss how transitions in the space of heterotic K3×T 2 compactifications are mapped by duality into transitions in the space of Type II compactifications on Calabi–Yau manifolds. We observe that… (More)

The complete structure of the moduli space of Calabi–Yau manifolds and the associated Landau-Ginzburg theories, and hence also of the corresponding lowenergy effective theory that results from (2,2)… (More)

We compute the SUSY-breaking soft terms in a magnetized D7-brane model with MSSM-like spectrum, under the general assumption of non-vanishing auxiliary fields of the dilaton and Kähler moduli. As a… (More)

We study heterotic E8 × E8 models that are dual to compactifications of Ftheory and type IIA string on certain classes of elliptically fibered Calabi-Yau manifolds. Different choices for the specific… (More)

We describe in detail the space of the two Kähler parameters of the Calabi–Yau manifold IP4 [18] by exploiting mirror symmetry. The large complex structure limit of the mirror, which corresponds to… (More)

In this work we classify the subalgebras satisfied by non-geometric Q-fluxes in type IIB orientifolds on T/(Z2 × Z2) with three moduli (S, T, U). We find that there are five subalgebras compatible… (More)

We report on a search for N = 2 heterotic strings that are dual candidates of type II compactifications on Calabi-Yau threefolds described as K3 fibrations. We find many new heterotic duals by using… (More)
