Early dark energy and the screening mechanism
H. Mohseni Sadjadi, V. Anari
In the early Universe, dark energy may have a non-negligible contribution. If this dark energy corresponds to an early cosmological constant, it leads to a late-time huge dark ener…
Constant-roll, cosmic acceleration, and massive neutrinos
V. Anari, H. Mohseni Sadjadi
We propose a model to describe the late-time cosmic acceleration in the context of the constant-roll model. By considering a coupling between massive neutrinos and the quintessence…
End of the constant-roll inflation, and the reheating temperature
H. Mohseni Sadjadi, V. Anari
By extending the potential, we propose a mechanism for the end of the constant-roll inflation and the subsequent reheating phase in the FLRW space-time. Based on astrophysical data…
Cosmic acceleration and de Sitter expansion in hybrid mass varying neutrino model
H. Mohseni Sadjadi, V. Anari
A nonminimally coupled hybrid dark energy model is introduced. The dark energy evolution is triggered by mass varying neutrinos. Quintessence evolution begins from an initial point…
Mass varying neutrinos, symmetry breaking, and cosmic acceleration
H. Mohseni Sadjadi, V. Anari
We introduce a new proposal for the onset of cosmic acceleration based on mass-varying neutrinos. When massive neutrinos become nonrelativistic, the symmetry breaks, and the…
