Constraining barrow entropy-based cosmology with power-law inflation [PDF]
European Physical Journal C: Particles and Fields, 2023 We study the inflationary era of the Universe in a modified cosmological scenario based on the gravity-thermodynamics conjecture with Barrow entropy instead of the usual Bekenstein–Hawking one.

Inflation and Fractional Quantum Cosmology [PDF]
Fractal and Fractional, 2022 The Wheeler–DeWitt equation for a flat and compact Friedmann–Lemaître–Robertson–Walker cosmology at the pre-inflation epoch is studied in the contexts of the standard and fractional quantum cosmology.

The Warm Inflation Story [PDF]
Universe, 2023 Warm inflation has normalized two ideas in cosmology, that in the early universe the initial primordial density perturbations generally could be of classical rather than quantum origin and that during inflation, particle production from interactions ...

Observational constraints on warm inflation in loop quantum cosmology [PDF]
Journal of Cosmology and Astroparticle Physics, 2019 By incorporating quantum aspects of gravity, Loop Quantum Cosmology (LQC) provides a self-consistent extension of the inflationary scenario, allowing for modifications in the primordial inflationary power spectrum with respect to the standard General ...

Triple unification of inflation, dark energy, and dark matter in two-scalar-field cosmology [PDF]
Physical Review D, 2020 A unified description of inflation, dark energy, and dark matter is presented within a two-scalar-field cosmological model. Inflation, assumed to be of the warm type, is driven by one of the scalar fields, which, shortly after the end of the inflationary

Cosmic Inflation, Quantum Information and the Pioneering Role of John S Bell in Cosmology [PDF]
Universe, 2019 According to the theory of cosmic inflation, the large scale structures observed in our Universe (galaxies, clusters of galaxies, Cosmic Background Microwave—CMB—anisotropy...) are of quantum mechanical origin.

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 ...

Precision cosmology and the stiff-amplified gravitational-wave background from inflation: NANOGrav, Advanced LIGO-Virgo and the Hubble tension [PDF]
Journal of Cosmology and Astroparticle Physics, 2021 The recent NANOGrav finding of a common-spectrum process has invited interpretations as possible evidence of a primordial stochastic gravitational-wave background (SGWB) stronger than predicted by standard inflation + ΛCDM.

G-bounce inflation: towards nonsingular inflation cosmology with galileon field [PDF]
Journal of High Energy Physics, 2015 A bstractWe study a nonsingular bounce inflation model, which can drive the early universe from a contracting phase, bounce into an ordinary inflationary phase, followed by the reheating process.
