Duration of inflation and conditions at the bounce as a prediction of effective isotropic loop quantum cosmology [PDF]
, 2013 Loop quantum cosmology with a scalar field is known to be closely linked with an inflationary phase. In this article, we study probabilistic predictions for the duration of slow-roll inflation, by assuming a minimalist massive scalar field as the main ...

Trans-Planckian censorship and inflationary cosmology [PDF]
Physical Review D, 2019 We study the implications of the recently proposed Trans-Planckian Censorship Conjecture (TCC) for early universe cosmology and in particular inflationary cosmology.

Cosmological Dynamics of Interacting Dark Energy and Dark Matter in f(Q)$f(Q)$ Gravity
Fortschritte der Physik, EarlyView.Abstract In this work, the behavior of interacting dark energy (DE) and dark matter (DM) within a model of f(Q)$f(Q)$ gravity is explored, employing the standard framework of dynamical system analysis. The power‐law f(Q)$f(Q)$ model is considered, incorporating two different forms of interacting DE and DM: 3αHρm$3\alpha H\rho _m$ and α3HρmρDE$\frac ...

Starobinsky-Like Inflation and Running Vacuum in the Context of Supergravity
Universe, 2016 We describe the primeval inflationary phase of the early Universe within a quantum field theoretical (QFT) framework that can be viewed as the effective action of vacuum decay in the early times. Interestingly enough, the model accounts for the “graceful

Remark on approximation in the calculation of the primordial spectrum generated during inflation [PDF]
Phys.Rev. D62 (2000) 087302, 2000 We re-examine approximations in the analytical calculation of the primordial spectrum of cosmological perturbation produced during inflation. Taking two inflation models (chaotic inflation and natural inflation) as examples, we numerically verify the accuracy of these approximations.

Cosmological Inflation: Theory and Observations [PDF]
Advanced Science Letters, 2009 In this article we review the theory of cosmological inflation with a particular focus on the beautiful connection it provides between the physics of the very small and observations of the very large. We explain how quantum mechanical fluctuations during the inflationary era become macroscopic density fluctuations which leave distinct imprints in the ...

Against interpretive exclusivism* Contre l'exclusivisme interprétatif
Journal of the Royal Anthropological Institute, EarlyView.Interpretive exclusivism is the dogma that we can only understand cultural systems by interpreting them, thereby ruling out causal explanations of cultural phenomena using scientific methods, for example based on measurement, comparison, and experiment.

Phenomenological Inflationary Model in Supersymmetric Quantum Cosmology
Universe, 2022 We consider the effective evolution of a phenomenological model from FLRW supersymmetric quantum cosmology with a scalar field. The scalar field acts as a clock and inflaton.

Gender, Feeling and the Making of Korean Christian Knowledge in Sengoku Japan*
Journal of Religious History, EarlyView.This essay explores the production of Korean Christian knowledge in Sengoku Japan by analysing narratives about a vision said to have been experienced by an evangelised Korean woman, which circulated within Jesuit correspondence from Japan and in subsequent publications.

Non-minimal Higgs Inflation and Frame Dependence in Cosmology [PDF]
, 2013 We investigate a very general class of cosmological models with scalar fields non-minimally coupled to gravity. A particular representative in this class is given by the non-minimal Higgs inflation model in which the Standard Model Higgs boson and the ...
