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 …

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 In the Emergence Proposal in Quantum Gravity it is conjectured that all light-
particle kinetic terms are absent in the fundamental ultraviolet theory and are generated by …

A bstract We study whether the universal runaway behaviour of stringy scalar potentials
towards infinite field distance limits can produce an accelerated expanding cosmology à la …

We investigate whether an accelerating universe can be realized as an asymptotic late-time
solution of Friedmann–Lemaître–Robertson–Walker (FLRW)-cosmology with multifield …

A bstract Based on Quantum Gravity arguments, it has been suggested that all kinetic terms
of light particles below the UV cut-off could arise in the IR via quantum (loop) corrections …

We propose an alternative refined de Sitter conjecture. It is given by a natural condition on a
combination of the first and second derivatives of the scalar potential. We derive our …

We provide a detailed discussion of the main theoretical and phenomenological challenges
of quintessence model building in any numerically controlled regime of the moduli space of …

A bstract We study runaway, kination-dominated epochs in string cosmology. We show how
the apparent classical decompactification runaway of the volume modulus, described by a …
