Vacua with Small Flux Superpotential

TLDR
This work describes a method for finding flux vacua of type IIB string theory in which the Gukov-Vafa-Witten superpotential is exponentially small, at large complex structure and weak string coupling.
Abstract
We describe a method for finding flux vacua of type IIB string theory in which the Gukov-Vafa-Witten superpotential is exponentially small. We present an example with ${W}_{0}\ensuremath{\approx}2\ifmmode\times\else\texttimes\fi{}{10}^{\ensuremath{-}8}$ on an orientifold of a Calabi-Yau hypersurface with $({h}^{1,1},{h}^{2,1})=(2,272)$, at large complex structure and weak string coupling.

I and i

Kevin Barraclough
- 08 Dec 2001 - 
TL;DR: There is, I think, something ethereal about i —the square root of minus one, which seems an odd beast at that time—an intruder hovering on the edge of reality.

Small Flux Superpotentials for Type IIB Flux Vacua Close to a Conifold

TL;DR: In this article, the authors generalize the mechanism proposed by Demirtas, Kim, McAllister and Moritz for the explicit construction of type IIB flux vacua with $|W_0|\ll 1$ to the region close to the conifold locus in the complex structure moduli space.

The Tadpole Problem

TL;DR: In this article, it was shown that the amount of charge induced by fluxes stabilizing all moduli grows faster than this, and is therefore larger than the allowed amount, and that moduli stabilization needs fluxes whose induced charge is (slightly smaller than) 1/2 of the number of moduli.

Conifold Vacua with Small Flux Superpotential

TL;DR: In this article, a method for finding flux vacua of type IIB string theory in which the flux superpotential is exponentially small and at the same time one or more complex structure moduli are stabilized near to conifold points is introduced.

On de Sitter string vacua from anti-d3-branes in the large volume scenario

TL;DR: In this paper, the de Sitter vacua is realized in concrete type IIB Calabi-Yau compactifications with an anti D3-brane at the tip of a warped throat of Klebanov-Strassler type.

De Sitter vacua in string theory

TL;DR: The metastable de Sitter vacua of type IIB string theory has been constructed in this article, which is a supersymmetric version of the ground state of the original ground state.

CFT's from Calabi–Yau four-folds

TL;DR: In this article, the authors consider F/M/Type IIA theory compactified to four, three, or two dimensions on a Calabi-Yau fourfold, and study the behavior near an isolated singularity in the presence of appropriate fluxes and branes.

Monodromy in the CMB: Gravity Waves and String Inflation

TL;DR: In this article, the authors present a simple mechanism for obtaining large-field inflation, and hence a gravitational wave signature, from string theory compactified on twisted tori, yielding predictions for the tilt of the power spectrum and the tensor-to-scalar ratio.

Gravity Waves and Linear Inflation from Axion Monodromy

TL;DR: In this article, a general mechanism for chaotic inflation driven by monodromy-extended closed-string axions is proposed, compatible with moduli stabilization and can be realized in many types of compactifications, including warped Calabi-Yau manifolds and more general Ricci-curved spaces.

Flux Compactification

TL;DR: A survey of the landscape of string and M theory vacua can be found in this article, where the authors discuss the potential for testable consequences of this picture, such as observable effects of moduli, constraints on early cosmology, and predictions for the scale of supersymmetry breaking.
