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 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 past two decades have seen transformative advances in cosmology and string theory.
Observations of the cosmic microwave background have revealed strong evidence for …

These lecture notes provide a pedagogical introduction, with exercises, to the techniques
used in attempts to construct vacua with stabilized moduli in string theory. The reader is only …

A bstract We initiate the systematic study of flux scalar potentials and their vacua by using
asymptotic Hodge theory. To begin with, we consider F-theory compactifications on Calabi …

A bstract We examine bounds on accelerated expansion in asymptotic regions of the moduli
space in string theory compactifications to four spacetime dimensions. While there are …

A bstract The continuous shift symmetry of axions is at the heart of several realizations of
inflationary models. In particular, axion monodromy inflation aims at achieving super …

Recently it has been conjectured that string theory does not allow for dS vacua or dS
extrema. To scrutinize such a conjecture, it is important to study concrete string theory …

We study the existence and stability of classical de Sitter solutions of type II supergravities
with parallel‐branes and orientifold‐planes. Together with the dilaton and volume scalar …

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 …
