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 …

Abstract The Nobel Prize winning confirmation in 1998 of the accelerated expansion of our
Universe put into sharp focus the need of a consistent theoretical model to explain the origin …

The past two decades have seen transformative advances in cosmology and string theory.
Observations of the cosmic microwave background have revealed strong evidence for …

In this review we present a thoroughly comprehensive survey of recent work on modified
theories of gravity and their cosmological consequences. Amongst other things, we cover …

We use Dirac's method for the quantization of constrained systems in order to quantize a
spatially flat Friedmann–Lemaître–Robertson–Walker spacetime in the context of f (Q) …

ABSTRACT The Wilkinson Microwave Anisotropy Probe (WMAP) 5-year data provide
stringent limits on deviations from the minimal, six-parameter Λ cold dark matter model. We …

Given the proliferation of bouncing models in recent years, we gather and critically assess
these proposals in a comprehensive review. The PLANCK data shows an unmistakably red …

Chern–Simons modified gravity is an effective extension of general relativity that captures
leading-order, gravitational parity violation. Such an effective theory is motivated by anomaly …

We present a simple mechanism for obtaining large-field inflation, and hence a gravitational
wave signature, from string theory compactified on twisted tori. For nil manifolds, we obtain a …

This is a pedagogical review on primordial non‐Gaussianities from inflation models. We
introduce formalisms and techniques that are used to compute such quantities. We review …
