In this review, a number of approaches to superstring cosmology which make use of key
features which distinguish string theory from point particle theories are discussed, with …

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 …

Our current best guess for a unified theory of gravitation and quantum field theory (string
theory) generically predicts a set of requirements for a consistently quantized theory, the …

A bstract A low-energy effective theory is said to be in the swampland if it does not have any
consistent UV completion inside a theory of quantum gravity. The natural question is if the …

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 Taking the anti-de Sitter minimum of KKLT and the large volume scenario at face
value, we argue for the existence of logarithmic quantum corrections to AdS swampland …

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 The Weak Gravity Conjecture (WGC) demands the existence of superextremal
particles in any consistent quantum theory of gravity. The standard lore is that these particles …

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 …
