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 ...

(No) Eternal Inflation in the Starobinsky Inflation Corrected by Higher Curvature Invariants
Astronomy, 2023 The swampland criteria in string theory assert the no eternal inflation scenario. This work studied the impact of generic gravitational quantum corrections on eternal inflation.

SciPost Physics, 2023 Non-trivial inflaton self-interactions can yield calculable signatures of primordial non-Gaussianity that are measurable in cosmic surveys. We calculate the non-Gaussian corrections to Stochastic Inflation within the framework of Soft de Sitter Effective

Eternal inflation, entropy bounds and the swampland [PDF]
European Physical Journal C: Particles and Fields, 2020 It has been suggested that low energy effective field theories should satisfy given conditions in order to be successfully embedded into string theory.

A smooth exit from eternal inflation?
Journal of High Energy Physics, 2018 The usual theory of inflation breaks down in eternal inflation. We derive a dual description of eternal inflation in terms of a deformed Euclidean CFT located at the threshold of eternal inflation.

The cosmological model of eternal inflation and the transition from chance to biological evolution in the history of life [PDF]
Biology Direct, 2007 Background Recent developments in cosmology radically change the conception of the universe as well as the very notions of "probable" and "possible". The model of eternal inflation implies that all macroscopic histories permitted by laws of physics are ...

Pre-inflation from the multiverse: can it solve the quadrupole problem in the cosmic microwave background? [PDF]
European Physical Journal C: Particles and Fields, 2018 We analyze a quantized toy model of a universe undergoing eternal inflation using a quantum-field-theoretical formulation of the Wheeler–DeWitt equation.

Journal of High Energy Physics, 2021 We consider multiverse models in two-dimensional linear dilaton-gravity theories as toy models of false vacuum eternal inflation. Coupling conformal matter we calculate the Von Neumann entropy of subregions. When these are sufficiently large we find that

QCD axion window and false vacuum Higgs inflation
Journal of High Energy Physics, 2020 The abundance of the QCD axion is known to be suppressed if the Hubble parameter during inflation, H inf , is lower than the QCD scale, and if the inflation lasts sufficiently long.

Islands and the de Sitter entropy bound
Journal of High Energy Physics, 2022 The de Sitter (dS) entropy bound gives the maximal number of e-folds that non-eternal inflation can last before violating the thermodynamical interpretation of dS space.
