Journal of Cosmology and Astroparticle Physics, 2023 Primordial black holes (PBH) may form from large cosmological perturbations, produced during inflation when the inflaton's velocity is sufficiently slowed down. This usually requires very flat regions in the inflationary potential.

On inflation and torsion in cosmology [PDF]
, 2005 In a recent letter by H. Davoudiasl, R. Kitano, T. Li and H. Murayama ``The new Minimal Standard Model'' (NMSM) was constructed that incorporates new physics beyond the Minimal Standard Model (MSM) of particle physics. The authors follow the principle of minimal particle content and therefore adopt the viewpoint of particle physicists. It is shown that

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 ...

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 ...

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 ...

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.

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

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.
