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, evading one well known difficulty of brane?antibrane scenarios. Careful consideration of the closed string moduli reveals a further obstacle: superpotential stabilization of the compactification volume typically modifies the inflaton potential and renders it too steep for inflation. We discuss the… Expand
Old inflation in string theory
We propose a stringy version of the old inflation scenario which does not require any slow-roll inflaton potential and is based on a specific example of string compactification with warped metric.Expand
Inflation in warped geometries
Abstract We argue that brane anti-brane inflation in string theory de-Sitter vacua of Kachru–Kallosh–Linde–Trivedi (KKLT) is captured by the dynamics of a D3-brane probe in the local KKLT modelExpand
The Standard Model and Inflation from String Theory
We review concrete attempts to derive both, the standard model and cosmological inflation from string theory. First, we describe a successful construction to obtain the realistic models from D‐branesExpand
Closer towards inflation in string theory
In brane inflation, the relative brane position in the bulk of a brane world is the inflaton. For branes moving in a compact manifold, the approximate translational (or shift) symmetry is necessaryExpand
Chasing brane inflation in string theory
We investigate the embedding of brane–antibrane inflation into a concrete type IIB string theory compactification with all moduli fixed. Specifically, we are considering a D3-brane, whose positionExpand
Fluxbrane Inflation
As a first step towards inflation in genuinely F-theoretic setups, we propose a scenario where the inflaton is the relative position of two 7-branes on holomorphic 4-cycles. Non-supersymmetric gaugeExpand
Braneworld inflation
We discuss various realizations of the four dimensional braneworld inflation in warped geometries of string theory. In all models the inflaton field is represented by a Dp probe brane scalarExpand
Tachyonic inflation in a warped string background
We analyze observational constraints on the parameter space of tachyonic inflation with a gaussian potential and discuss some predictions of this scenario. As was shown by Kofman and Linde, it isExpand
Wilson line inflation
We present a general setup for inflation in string theory where the inflaton field corresponds to Wilson lines in compact space in the presence of magnetic fluxes. T-dualities and limits on the valueExpand
Inflation from wrapped branes
We show that the use of higher dimensional wrapped branes can significantly extend the inflaton field range compared to brane inflation models which use $D3$-branes. We construct a simpleExpand


D-brane Inflation
We discuss a calculable version of brane inflation, in which a set of parallel D-brane and anti-D-brane worlds, initially displaced in extra dimension, slowly attract each other. In the effectiveExpand
Hybrid inflation and brane–antibrane system
We study a string theory inspired model for hybrid inflation in the context of a brane–antibrane system partially compactified on a compact submanifold of (a caricature of) a Calabi–Yau manifold. TheExpand
Brane Inflation
We present a novel inflationary scenario in theories with low scale (TeV) quantum gravity, in which the standard model particles are localized on the branes whereas gravity propagates in the bulk ofExpand
Inflationary cosmology in the central region of string and M-theory moduli space
The "central" region of moduli space of M- and string theories is where the string coupling is about unity and the volume of compact dimensions is about the string volume. Here we argue that in thisExpand
The Inflationary Brane-Antibrane Universe
We show how the motion through the extra dimensions of a gas of branes and antibranes can, under certain circumstances, produce an era of inflation as seen by observers trapped on a 3-brane, with theExpand
Branes and inflationary cosmology
Abstract We discuss a brane based inflationary scenario in which an initially non-supersymmetric configuration involving a D4 brane is dynamically transformed into a supersymmetric one in aExpand
De Sitter vacua in string theory
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. ByExpand
String theory and hybrid inflation / acceleration
We find a description of hybrid inflation in (3+1)-dimensions using brane dynamics of Hanany-Witten type. P-term inflation/acceleration of the universe with the hybrid potential has a slow-roll deExpand
Brane interaction as the origin of inflation
We reanalyze brane inflation with brane-brane interactions at an angle, which include the special case of brane-anti-brane interaction. If nature is described by a stringy realization of the braneExpand
Some aspects of brane inflation
Abstract The inflaton potential in four-dimensional theory is rather arbitrary, and fine-tuning is required generically. By contrast, inflation in the brane world scenario has the interesting featureExpand
