Abstract The standard Λ Cold Dark Matter (ΛCDM) cosmological model provides a good
description of a wide range of astrophysical and cosmological data. However, there are a …

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 …

Dynamical dark energy has gained renewed interest due to recent theoretical and
observational developments. In the present paper, we focus on a string-motivated dark …

Inspired by the recent conjecture originated from graduated dark energy that the Universe
has recently transitioned from anti–de Sitter vacua to de Sitter vacua, we extend the …

A bstract We explore the possibility that our universe's current accelerated expansion is
explained by a quintessence model with an exponential scalar potential, V= V 0 e− λ ϕ …

We explore cosmological constraints on the sum of the three active neutrino masses M ν in
the context of dynamical dark energy (DDE) models with equation of state (EoS) …

In this article, we study the implications of string swampland criteria for dark energy in view
of ongoing and future cosmological observations. If string theory should be the ultimate …

Persisting tensions between high-redshift and low-redshift cosmological observations
suggest the dark energy sector of the Universe might be more complex than the positive …

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 …
