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 …

A number of challenges to the standard Λ CDM model have been emerging during the past
few years as the accuracy of cosmological observations improves. In this review we discuss …

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 …

This article reviews recent developments in tests of fundamental physics using atoms and
molecules, including the subjects of parity violation, searches for permanent electric dipole …

Dark matter represents currently an outstanding problem in both cosmology and particle
physics. In this review we discuss the possible explanations for dark matter and the …

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 …

After a decade and a half of research motivated by the accelerating universe, theory and
experiment have reached a certain level of maturity. The development of theoretical models …

The recent result of the Dark Energy Spectroscopic Instrument (DESI) in combination with
other cosmological data shows evidence of the evolving dark energy parametrized by the w …

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 …

A century ago, Einstein formulated his elegant and elaborate theory of General Relativity,
which has so far withstood a multitude of empirical tests with remarkable success …
