More Dual Fluxes and Moduli Fixing
We generalize the recent proposal that invariance under T-duality leads to additional non-geometric fluxes required so that superpotentials in type IIA and type IIB orientifolds match. We show thatExpand

Duality between the webs of heterotic and type II vacua
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 thatExpand

Mirror Symmetry for Two Parameter Models - II *
We describe in detail the space of the two Kahler parameters of the Calabi-Yau manifold P4(1,1,1,6,9)[18] by exploiting mirror symmetry. The large complex structure limit of the mirror, whichExpand

Mirror Symmetry for Two Parameter Models -- I
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 moduliExpand

Fluxes, moduli fixing and MSSM-like vacua in a simple IIA orientifold
We study the effects of adding RR, NS and metric fluxes on a T^6/(\Omega (-1)^{F_L} I_3) Type IIA orientifold. By using the effective flux-induced superpotential we obtain Minkowski or AdS vacua withExpand

Periods for Calabi-Yau and Landau-Ginzburg vacua☆
Abstract The complete structure of the moduli space of Calabi-Yau manifolds and the associated Landau-Ginzburg theories, and hence also of the corresponding low-energy effective theory that resultsExpand

Relating double field theory to the scalar potential of N = 2 gauged supergravity
A bstractThe double field theory action in the flux formulation is dimensionally reduced on a Calabi-Yau three-fold equipped with non-vanishing type IIB geometric and non-geometric fluxes. First, weExpand

SUSY-breaking Soft Terms in a MSSM Magnetized D7-brane Model
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 Kahler moduli. As aExpand

Flux and instanton effects in local F-theory models and hierarchical fermion masses
We study the deformation induced by fluxes and instanton effects on Yukawa couplings involving 7-brane intersections in local F-theory constructions. In the absence of non-perturbative effects,Expand
