Topics in Cosmology—Clearly Explained by Means of Simple Examples
Universe, 2022 This is a very comprehensible review of some key issues in modern cosmology. Simple mathematical examples and analogies are used, whenever available. The starting point is the well-known Big Bang cosmology (BBC).

Superstring cosmology — a complementary review [PDF]
Journal of Cosmology and Astroparticle Physics, 2023 In this review, a number of approaches to superstring cosmology which make use of key features which distinguish string theory from point particle theories are discussed, with particular emphasis on emergent scenarios.

Bounce inflation cosmology with Standard Model Higgs boson [PDF]
, 2015 It is of great interest to connect cosmology in the early universe to the Standard Model of particle physics. In this paper, we try to construct a bounce inflation model with the standard model Higgs boson, where the one loop correction is taken into ...

European Physical Journal C: Particles and Fields, 2021 We study cosmological inflation and its dynamics in the framework of the Randall–Sundrum II brane model. In particular, we analyze in detail four representative small-field inflationary potentials, namely Natural inflation, Hilltop inflation, Higgs-like ...

Entropic Inflation in Presence of Scalar Field
Universe, 2023 In spirit of the recently proposed four-parameter generalized entropy of apparent horizon, we investigate inflationary cosmology where the matter field inside of the horizon is dominated by a scalar field with a power law potential (i.e., the form of ϕn ...

New Anisotropic Exact Solution in Multifield Cosmology
Universe, 2021 In the case of two-scalar field cosmology, and specifically for the Chiral model, we determine an exact solution for the field equations with an anisotropic background space.

Loop quantum cosmology: relation between theory and observations [PDF]
, 2023 This chapter provides a review of the frameworks developed for cosmological perturbation theory in loop quantum cosmology, and applications to various models of the early universe including inflation, ekpyrosis and the matter bounce, with an emphasis on ...

Minimal decoherence from inflation [PDF]
Journal of Cosmology and Astroparticle Physics, 2022 We compute the rate with which super-Hubble cosmological fluctuations are decohered during inflation, by their gravitational interactions with unobserved shorter-wavelength scalar and tensor modes. We do so using Open Effective Field Theory methods, that

How Generic Is Eternal Inflation?
Sci, 2022 Everlasting inflation has far-reaching implications for cosmology and the standing of self-localizing inferences made by observers, which have been subjects of renewed interest in light of the growing acceptance of theory landscapes and the attendant ...

Bootstrapping multi-field inflation: non-Gaussianities from light scalars revisited [PDF]
Journal of Cosmology and Astroparticle Physics, 2022 Primordial non-Gaussianities from multi-field inflation are a leading target for cosmological observations, because of the possible large correlations generated between long and short distances.
