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 …

We review in detail a number of approaches that have been adopted to try and explain the
remarkable observation of our accelerating universe. In particular we discuss the arguments …

We study constraints imposed by two proposed string Swampland criteria on cosmology.
These criteria involve an upper bound on the range traversed by scalar fields as well as a …

The recently introduced swampland criterion for de Sitter [17] can be viewed as a
(hierarchically large) bound on the smallness of the slow roll parameter 𝜖 V. This leads us to …

A bstract The Distance Conjecture holds that any infinite-distance limit in the scalar field
moduli space of a consistent theory of quantum gravity must be accompanied by a tower of …

Physics welcomes the idea that space contains energy whose gravitational effect
approximates that of Einstein's cosmological constant, Λ; today the concept is termed dark …

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 …

Beyond Einstein's Gravity is a graduate level introduction to extended theories of gravity and
cosmology, including variational principles, the weak-field limit, gravitational waves …

There is strong evidence that the area of any surface limits the information content of
adjacent spacetime regions, at 1.4× 10 69 bits per square meter. This article reviews the …
