Hill-climbing dark inflation
Michal Artymowski, Zygmunt Lalak, Kin-Ya Oda
Within the framework of the scalar-tensor theory we consider a hill-climbing inflation, in which the effective Planck mass increases in time. We obtain the Einstein frame potential…
Quantum Hubble horizon
Michal Artymowski, Jakub Mielczarek
The article addresses a possibility of obtaining cosmologically relevant effects from the quantum nature of the Hubble horizon. Following the observation made by E.~Bianchi and C.~…
New parameterization for unified dark matter and dark energy
Zahra Davari, Mohammad Malekjani, Michal Artymowski
In this paper we investigate a new phenomenological parameterization for unified dark matter and dark energy based on the polynomial expansion of the barotropic equation of state p…
