De Sitter vacua in string theory

- S. Kachru, R. Kallosh, Andrei Linde, S. Trivedi
- Mathematics
- 29 January 2003

We outline the construction of metastable de Sitter vacua of type IIB string theory. Our starting point is highly warped IIB compactifications with nontrivial NS and RR three-form fluxes. By… Expand

Hierarchies from fluxes in string compactifications

- S. Giddings, S. Kachru, J. Polchinski
- Mathematics
- 10 May 2001

Warped compactifications with significant warping provide one of the few known mechanisms for naturally generating large hierarchies of physical scales. We demonstrate that this mechanism is… Expand

Towards inflation in string theory

- MathematicsJournal of Cosmology and Astroparticle Physics
- 7 August 2003

We investigate the embedding of brane inflation into stable compactifications of string theory. At first sight a warped compactification geometry seems to produce a naturally flat inflaton potential,… Expand

Geometric singularities and enhanced gauge symmetries

Brane/Flux Annihilation and the String Dual of a Non-Supersymmetric Field Theory

- S. Kachru, J. Pearson, H. Verlinde
- Physics
- 20 December 2001

We consider the dynamics of p anti-D3 branes inside the Klebanov-Strassler geometry, the deformed conifold with M units of RR 3-form flux around the S3. We find that for p << M the system relaxes to… Expand

Gravity Duals of Lifshitz-Like Fixed Points

- S. Kachru, Xiao Liu, Michael Mulligan
- Physics
- 13 August 2008

We find candidate macroscopic gravity duals for scale-invariant but non-Lorentz invariant fixed points, which do not have particle number as a conserved quantity. We compute two-point correlation… Expand

Observational signatures and non-Gaussianities of general single-field inflation

- Xingang Chen, Min-xin Huang, S. Kachru, G. Shiu
- Physics
- 3 May 2006

We perform a general study of primordial scalar non-Gaussianities in single field inflationary models. We consider models where the inflaton Lagrangian is an arbitrary function of the scalar field… Expand

Aspects of holography for theories with hyperscaling violation

- Xi Dong, Sarah M. Harrison, S. Kachru, G. Torroba, Huajia Wang
- Physics
- 9 January 2012

A bstractWe analyze various aspects of the recently proposed holographic theories with general dynamical critical exponent z and hyperscaling violation exponent θ. We first find the basic constraints… Expand

Type IIA Moduli Stabilization

- O. Dewolfe, A. Giryavets, S. Kachru, W. Taylor
- Mathematics
- 18 May 2005

We demonstrate that flux compactifications of type IIA string theory can classically stabilize all geometric moduli. For a particular orientifold background, we explicitly construct an infinite… Expand

N-flation

- S. Dimopoulos, S. Kachru, J. McGreevy, J. Wacker
- Physics
- 21 July 2005

The presence of many axion fields in four-dimensional string vacua can lead to a simple, radiatively stable realization of chaotic inflation.
