Systematics 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 potentialExpand

Large-volume flux compactifications: Moduli spectrum and D3/D7 soft supersymmetry breaking
We present an explicit calculation of the spectrum of a general class of string models, corresponding to Calabi-Yau flux compactifications with h1,2 > h1,1 > 1 with leading perturbative andExpand

De Sitter string vacua from supersymmetric D-terms
We propose a new mechanism for obtaining de Sitter vacua in type-IIB string theory compactified on (orientifolded) Calabi-Yau manifolds similar to those recently studied by Kachru, Kallosh, Linde andExpand

D-Branes at Singularities : A Bottom-Up Approach to the String Embedding of the Standard Model
We propose a bottom-up approach to the building of particle physics models from string theory. Our building blocks are Type II D-branes which we combine appropriately to reproduce desirable featuresExpand

Duality symmetries from non-abelian isometries in string theory
Abstract In string theory it is known that abelian isometries in the σ-model lead to target space duality. We generalize this duality to background with non-abelian isometries. The procedure weExpand

Kahler moduli inflation
We show that under general conditions there is at least one natural inflationary direction for the Kahler moduli of type-IIB flux compactifications. This requires a Calabi-Yau which hasExpand

Soft SUSY breaking terms for chiral matter in IIB string compactifications
This paper develops the computation of soft supersymmetry breaking terms for chiral D7 matter fields in IIB Calabi-Yau flux compactifications with stabilised moduli. We determine explicit expressionsExpand

Fibre inflation: observable gravity waves from IIB string compactifications
We introduce a simple string model of inflation, in which the inflaton field can take trans-Planckian values while driving a period of slow-roll inflation. This leads naturally to a realisation ofExpand

General analysis of LARGE Volume Scenarios with string loop moduli stabilisation
We study the topological conditions for general Calabi-Yaus to get a non-supersymmetric AdS exponentially large volume minimum of the scalar potential in flux compactifications of IIB string theory.Expand

Astrophysical and cosmological implications of large volume string compactifications
We study the spectrum, couplings and cosmological and astrophysical implications of the moduli fields for the class of Calabi–Yau IIB string compactifications for which moduli stabilisation leads toExpand
