Non-minimally coupled scalar field cosmology on the phase plane
Orest Hrycyna, Marek Szydlowski
In this publication we investigate dynamics of a flat FRW cosmological model with a non-minimally coupled scalar field with the coupling term in the scalar field action.…
Scalar field cosmology in the energy phase-space -- unified description of dynamics
Marek Szydlowski, Orest Hrycyna
In this letter we apply dynamical system methods to study all evolutional paths admissible for all initial conditions of the FRW cosmological model with a non-minimally coupled to…
From model dynamics to oscillating dark energy parameterisation
Aleksandra Kurek, Orest Hrycyna, Marek Szydlowski
We develop here a relatively simple description of dark energy based on the dynamics of non-minimally coupled to gravity phantom scalar field which, in limit, corresponds to cosmol…
Effects of the quantisation ambiguities on the Big Bounce dynamics
Orest Hrycyna, Jakub Mielczarek, Marek Szydlowski
In this paper we investigate dynamics of the modified loop quantum cosmology models using dynamical systems methods. Modifications considered come from the choice of the different…
