The compiled record

The paper's own sentences, arranged. Each label is drawn from a closed vocabulary; the number beside it is the probability the classifier gave that label. Numbers in the tables are the authors', checked by code. No sentence in this record was written by a model.

The abstract, sentence by sentence

arXiv listing abstract v1. Results and the main claim are underlined; .

We provide a detailed study of reheating in the kination regime where particle content is created by gravitational production of massive scalars mutually interacting with a massless scalar field. The produced particles subsequently decay into massless particles eventually reheating the Universe. We aim for a more precise picture using Boltzmann equations and decay rates obtained by methods of quantum field theory in curved spacetime. By numerical calculations it is found that after inflation the Universe ends up being dominated by ordinary matter for a while before the radiation dominated era. The reheating temperature itself is found to be in the $10^6-10^{12}\ \text{GeV}$ regime.

By numerical calculations it is found that after inflation the Universe ends up being dominated by ordinary matter for a while before the radiation dominated era.

  • Gravitational production of (DM) candidates was studied for various candidates and within different settings: heavy (DM) particles [ref] , production from inflaton oscillations or oscillatory backgrounds [ref] , for “stiff” equations of state in [ref] , or during reheating [ref] .

    Non-adiabatic cosmological production of ultra-light Dark Matter · Introduction · 0.99

  • In this context, gravitational reheating [ref] is a compelling mechanism by which the interaction of a quantum field coupled with gravity generates massive particles which decay into standard model (SM) particles and other forms of matter and radiation, thereby reheating the Universe.

    Gravitational reheating formulas and bounds in oscillating backgrounds · Introduction · 0.88

  • Gravitational production has been studied for various candidates and different cosmological backgrounds: heavy particles produced during inflation [ref] , via inflaton oscillations [ref] , reheating [ref] , or via cosmological expansion during an era with a particular equation of state [ref] , and more recently ultralight bosonic particles cosmologically produced during inflation and a post-inflation radiation era [ref] .
