Generalising axion-like particle as the curvaton: sourcing primordial density perturbation and non-Gaussianities by Anish Ghoshal, Abhishek Naskar

“…The ALP is a spectator field during inflation but it starts to oscillate and dominates the energy density of the universe after inflation ends, thereby sourcing isocurvature perturbations, while standard curvature fluctuations from the inflaton are assumed to be sub-dominant. …”

Will There Be Future Deceleration? A Study of Particle Creation Mechanism in Nonequilibrium Thermodynamics by Supriya Pan, Subenoy Chakraborty

“…Motivated by thermodynamical point of view, cosmological solutions are evaluated for the particle creation rates in three cosmic phases, namely, inflation, matter dominated era, and present late time acceleration. …”

Soliton foam formation in the early Universe by A.A. Kirillov, B.S. Murygin, V.V. Nikulin

“…The realistic initial conditions are obtained through the simulation of multiple quantum fluctuations during the inflation epoch. The initial field distributions allow to form local soliton clusters in the early Universe without the need for the thermal production of a soliton network throughout the Universe. …”

Generalization of the Randall-Sundrum Model Using Gravitational Model F(T,Θ) by S. Davood Sadatian, S. M. Hosseini

“…The results showed that inflation and the dark energy-dominated stage can be realized in this model. …”

Irreversible Thermodynamic Description of Dark Matter and Radiation Creation during Inflationary Reheating by Juntong Su, Tiberiu Harko, Shi-Dong Liang

“…Once the energy density of the scalar field becomes negligible with respect to the matter densities, the expansion of the Universe decelerates, and inflation has a graceful exit.…”

Reconstruction of the scalar field potential in nonmetricity gravity through Gaussian processes by Gaurav N. Gadbail, Sanjay Mandal, P.K. Sahoo, Kazuharu Bamba

“…The accelerated expansion of the universe has been widely confirmed, posing challenges to the standard Λ CDM model, particularly the cosmological coincidence problem. This has motivated the exploration of modified gravity theories, including nonmetricity gravity, which explains cosmic acceleration without dark energy. …”
