Inflation and Fractional Quantum Cosmology
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.

Why do Public Debates Escalate? Trigger Points and the Moral Dynamics of “Hot Politics”
The British Journal of Sociology, EarlyView.ABSTRACT Escalating, emotionally charged, and moralized forms of controversy are a central feature of contemporary politics. Our study develops a framework for understanding how political debates between ordinary citizens become heated; why certain issues provoke particularly strong emotions; and how this affective potential is weaponized by ...

The method of generating functions in exact scalar field inflationary cosmology
European Physical Journal C: Particles and Fields, 2018 The construction of exact solutions in scalar field inflationary cosmology is of growing interest. In this work, we review the results which have been obtained with the help of one of the most effective methods, viz., the method of generating functions ...

Principles, Progress and Problems in Inflationary Cosmology [PDF]
, 2002 Inflationary cosmology has become one of the cornerstones of modern cosmology. Inflation was the first theory within which it was possible to make predictions about the structure of the Universe on large scales, based on causal physics.

Trans-Planckian Physics and Inflationary Cosmology [PDF]
, 2002 Due to the quasi-exponential red-shifting which occurs during an inflationary period in the very early Universe, wavelengths which at the present time correspond to cosmological lengths are in general sub-Planckian during the early stages of inflation ...

Singularities in Inflationary Cosmological Models [PDF]
Universe, 2021 Due to the accelerated expansion of the universe, the possibilities for the formation of singularities has changed from the classical Big Bang and Big Crunch singularities to include a number of new scenarios. In recent papers it has been shown that such singularities may appear in inflationary cosmological models with a fractional power scalar field ...

Meteoritics &Planetary Science, EarlyView.Abstract A core drilled through shocked and faulted Archean granitoid gneisses and dolerites in the eroded peak ring of the 70–80 km diameter Morokweng impact structure intersects multiple centimeter‐ to meter‐wide clastic‐matrix breccias containing a polymict clast population of lithic and mineral clasts and altered, millimeter‐ to centimeter ‐size ...

European Physical Journal C: Particles and Fields, 2019 Mimetic gravity can be described as a formulation capable of mimicking different evolutionary scenarios regarding the universe dynamics. Notwithstanding its initial aim of producing a similar evolution to the one expected from the dark components of the ...

Cosmology of the Very Early Universe
, 2010 In these lectures I focus on early universe models which can explain the currently observed structure on large scales. I begin with a survey of inflationary cosmology, the current paradigm for understanding the origin of the universe as we observe it ...
