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 …

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 …

It has been notoriously difficult to construct a meta-stable de Sitter (dS) vacuum in string
theory in a controlled approximation. This suggests the possibility that meta-stable dS …

De Sitter solutions have been recently conjectured to be incompatible with quantum gravity.
In this paper we critically assess the progress and challenges of different mechanisms to …

We review the advanced version of the KKLT construction and pure de Sitter supergravity,
involving a nilpotent multiplet, with regard to various conjectures that de Sitter state cannot …

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 …

We analyze to which extent the KKLT proposal for the construction of de Sitter vacua in
string theory is quantitatively controlled. Our focus is on the quality of the 10d supergravity …

We give an overview of moduli stabilization in compactifications of string theory. We
summarize current methods for construction and analysis of vacua with stabilized moduli …

We find a mechanism by which antibranes placed in a warped deformed conifold throat can
destroy the stabilization of the size of the sphere at the tip, collapsing it to zero size. This …

A bstract Type II string theory and M-theory admit flux configurations that break
supersymmetry below the Kaluza-Klein scale. These backgrounds play a central role in most …
