Systematics of moduli stabilisation in Calabi-Yau flux compactifications

- V. Balasubramanian, Per Berglund, J. Conlon, F. Quevedo
- Physics
- 4 February 2005

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… Expand

De Sitter string vacua from supersymmetric D-terms

- C. Burgess, Renata Kallosh, F. Quevedo
- Physics
- 18 September 2003

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 and… Expand

Fibre inflation: observable gravity waves from IIB string compactifications

- M. Cicoli, C. Burgess, F. Quevedo
- Physics
- 5 August 2008

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 of… Expand

Kahler moduli inflation

- J. Conlon, F. Quevedo
- Physics
- 1 September 2005

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 has… Expand

Duality symmetries from non-abelian isometries in string theory

- X. Ossa, F. Quevedo
- Physics
- 5 October 1992

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 we… Expand

Systematics of string loop corrections in type IIB Calabi-Yau flux compactifications

- M. Cicoli, J. Conlon, F. Quevedo
- Physics
- 14 August 2007

We study the behaviour of the string loop corrections to the N = 1 4D supergravity Kahler potential that occur in flux compactifications of IIB string theory on general Calabi-Yau three-folds. We… Expand

Towards a Naturally Small Cosmological Constant from Branes in 6D Supergravity

- Y. Aghababaie, C. Burgess, S. Parameswaran, F. Quevedo
- Physics
- 29 April 2003

Abstract We investigate the possibility of self-tuning of the effective 4D cosmological constant in 6D supergravity, to see whether it could naturally be of order 1/r4 when compactified on two… Expand

Astrophysical and cosmological implications of large volume string compactifications

- J. Conlon, F. Quevedo
- Physics
- 23 May 2007

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 to… Expand

General analysis of LARGE Volume Scenarios with string loop moduli stabilisation

- M. Cicoli, J. Conlon, F. Quevedo
- Physics
- 7 May 2008

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

Realistic D-brane models on warped throats: Fluxes, hierarchies and moduli stabilization

- J.F.G. Cascales, M. P. G. D. Moral, F. Quevedo, A. Uranga
- Physics
- 4 December 2003

We describe the construction of string theory models with semirealistic spectrum in a sector of (anti) D3-branes located at an orbifold singularity at the bottom of a highly warped throat geometry,… Expand
