Negative Energy Density in Calabi-Yau Compactifications
We show that a large class of supersymmetric compactifications, including all simply connected Calabi-Yau and G2 manifolds, have classical configurations with negative energy density as seen from four dimensions. In fact, the energy density can be arbitrarily negative – it is unbounded from below. Nevertheless, positive energy theorems show that the total ADM energy remains positive. Physical c...
متن کاملMirror Symmetry in Generalized Calabi–Yau Compactifications
We discuss mirror symmetry in generalized Calabi–Yau compactifications of type II string theories with background NS fluxes. Starting from type IIB compactified on Calabi– Yau threefolds with NS three-form flux we show that the mirror type IIA theory arises from a purely geometrical compactification on a different class of six-manifolds. These mirror manifolds have SU(3) structure and are terme...
متن کاملModular Constraints on Calabi-Yau Compactifications
We derive global constraints on the non-BPS sector of supersymmetric 2d sigmamodels whose target space is a Calabi-Yau manifold. When the total Hodge number of the Calabi-Yau threefold is sufficiently large, we show that there must be non-BPS primary states whose total conformal weights are less than 0.656. Moreover, the number of such primary states grows at least linearly in the total Hodge n...
متن کاملString compactifications on Calabi-Yau stacks
In this paper we study string compactifications on Deligne-Mumford stacks. The basic idea is that all such stacks have presentations to which one can associate gauged sigma models, where the group gauged need be neither finite nor effectively-acting. Such presentations are not unique, and lead to physically distinct gauged sigma models; stacks classify universality classes of gauged sigma model...
متن کاملSystematics of Moduli Stabilisation in Calabi-Yau Flux Compactifications
We study the large volume limit of the scalar potential in Calabi-Yau flux compactifications of type IIB string theory. Under general circumstances there exists a limit in which the potential approaches zero from below, with an associated non-supersymmetric AdS minimum at exponentially large volume. Both this and its de Sitter uplift are tachyon-free, thereby fixing all Kähler and complex struc...
