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 ...

Supersymmetric small-field inflation with tribrid superpotentials [PDF]

, 2016
In this thesis, we study supersymmetric models of tribrid inflation and new inflation, both of which can be realized with a tribrid superpotential. In the first part, we focus on tribrid inflation, deriving relations between cosmological observables ...

Alternatives to cosmological inflation [PDF]

Physics Today, 2008
Inflationary cosmology is elegant and can claim significant predictive successes. But its attendant difficulties have motivated competing scenarios that also agree with observation.

Probing inflation with CMB polarization [PDF]

, 2008
We summarize the utility of precise cosmic microwave background (CMB) polarization measurements as probes of the physics of inflation. We focus on the prospects for using CMB measurements to differentiate various inflationary mechanisms. In particular, a

Reheating in holographic cosmology and connecting to Λ-MSSM constructions for particle physics

Journal of High Energy Physics, 2021
In this paper we model the transition from the non-geometric holographic cosmology regime, to the usual radiation dominated (RD) cosmology, known as reheating in the case of (perturbative) inflation.

Inflation and precision cosmology [PDF]

Brazilian Journal of Physics, 2004
A brief review of inflation is presented. After having demonstrated the generality of the inflationary mechanism, the emphasize is put on its simplest realization, namely the single field slow-roll inflationary scenario. Then, it is shown how, concretely, one can calculate the predictions of a given model of inflation.

Effect of inflation on anisotropic cosmologies [PDF]

Physical Review D, 1986
We study the effects of anisotropic cosmologies on inflation. By properly formulating the field equations it is possible to show that any model that undergoes sufficient inflation will become isotropic on scales greater than the horizon today. Furthermore, we shall show that it takes a very long time for anisotropies to become visible in the observable

MSSM inflation and cosmological attractors [PDF]

International Journal of Geometric Methods in Modern Physics, 2018
Inflationary scenarios motivated by the minimal supersymmetric standard model (MSSM) where five scalar fields are non-minimally coupled to gravity are considered. The potential of the model and the function of non-minimal coupling are polynomials of two Higgs doublet convolutions.
