Nongeometric Flux Compactifications
We investigate a simple class of type II string compactifications which incorporate nongeometric “fluxes” in addition to “geometric flux” and the usual H-field and R-R fluxes. These compactifications are nongeometric analogues of the twisted torus. We develop T-duality rules for NS-NS geometric and nongeometric fluxes, which we use to construct a superpotential for the dimensionally reduced fou...
متن کاملWEAKLY-coupled IIA Flux Compactifications
We study compactifications of type IIA string theory on Calabi-Yau manifolds that are mirror to a subset of the type IIB LARGE-volume models. A combination of flux, α corrections and non-perturbative effects stabilises the moduli in a non-supersymmetric AdS vacuum. This vacuum has the feature that the (ten-dimensional) string coupling is exponentially small which can naturally lead to a TeV sup...
متن کاملDynamics of Warped Flux Compactifications
We discuss the four dimensional effective action for type IIB flux compactifications, and obtain the quadratic terms taking warp effects into account. The analysis includes both the 4-d zero modes and their KK excitations, which become light at large warping. We identify an ‘axial’ type gauge for the supergravity fluctuations, which makes the four dimensional degrees of freedom manifest. The ot...
متن کاملPhysics of String Flux Compactifications
We provide a qualitative review of flux compactifications of string theory, focusing on broad physical implications and statistical methods of analysis.
متن کاملFlux Compactifications: Stability and Implications for Cosmology
We study the dynamics of the size of an extra-dimensional manifold stabilised by fluxes. Inspecting the potential for the 4D field associated with this size (the radion), we obtain the conditions under which it can be stabilised and show that stable compactifications on hyperbolic manifolds necessarily have a negative fourdimensional cosmological constant, in contradiction with experimental obs...
