We review applications of string theory to cosmology, from primordial times to the present-
day accelerated expansion. Starting with a brief overview of cosmology and string …

The Swampland program aims to distinguish effective theories which can be completed into
quantum gravity in the ultraviolet from those which cannot. This article forms an introduction …

We consider single-field inflation in light of string-motivated'swampland'conjectures
suggesting that effective scalar field theories with a consistent UV completion must have …

In the simplest picture, the masses of string axions populating the axiverse depend on two
parameters: the supersymmetry-breaking scale M susy and the action S of the string …

Recently, arguments for a refined de Sitter conjecture were put forward in [1]. Using the large
distance conjecture of [2], the authors provide evidence for this dS conjecture in asymptotic …

Motivated by its potential use as a starting point for solving various cosmological constant
problems, we study F‐theory compactified on the warped product where Y8 is a manifold …

A bstract We present strong evidence that the tree level slow roll bounds of arXiv:
1807.05193 and arXiv: 1810.05506 are valid, even when the tachyon has overlap with the …

A bstract It was recently argued that the swampland distance conjecture rules out dS vacua
at parametrically large field distances. We point out that this conclusion can in principle be …

We study the phenomenology of a recent string construction with a quantum mechanically
stable dark energy. A mild supersymmetry protects the vacuum energy but also allows TeV …

A bstract We discuss the properties of massive type IIA flux compactifications. In particular,
we investigate in which case one can obtain dS vacua at large volume and small coupling …
