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.

Recent Developments in Warm Inflation [PDF]
Universe, 2023 Warm inflation, its different particle physics model implementations, and the implications of dissipative particle production for its cosmology are reviewed.

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 ...

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 in the Rényi cosmology [PDF]
Modern Physics Letters A, 2019 The description of the accelerated phases for the current and primordial cosmos has been obtained in the framework of Rényi cosmology. The results show that corrections to the Friedmann equations, originated from differences between Rényi and Bekenstein ...

Inflation in loop quantum cosmology [PDF]
Physical Review D, 2018 We develop a consistent analytic approach to determine the conditions under which slow roll inflation can arise when the inflaton is the same scalar field that is responsible for the bounce in Loop Quantum Cosmology (LQC).

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. They are nothing but vacuum

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.
