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.

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 ...

Relativistic Cosmology with an Introduction to Inflation [PDF]
Universe, 2021 In this review article, the study of the development of relativistic cosmology and the introduction of inflation in it as an exponentially expanding early phase of the universe is carried out.

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).

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.

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

Cosmology, inflation, and the physics of nothing [PDF]
, 2003 These four lectures cover four topics in modern cosmology: the cosmological constant, the cosmic microwave background, inflation, and cosmology as a probe of physics at the Planck scale. The underlying theme is that cosmology gives us a unique window on the ``physics of nothing,'' or the quantum-mechanical properties of the vacuum.

Cosmological parameters in noncommutative inflation [PDF]
Physics Letters B, 2004 We investigate how the uncertainty of noncommutative spacetime could explain the WMAP data. For this purpose, the spectrum is divided into the IR and UV region. We introduce a noncommutative parameter of $ _0$ in the IR region and a noncommutative parameter of $ _0$ in the UV region.
