Unifying dark components and crossing the phantom divide with a classical Dirac field
Mauricio Cataldo, Luis P. Chimento
In this paper we consider a spatially flat Friedmann-Robertson-Walker (FRW) cosmological model whit cosmological constant, containing a stiff fluid and a classical Dirac field. The…
Unified model of baryonic matter and dark components
Luis Chimento, Monica Forte
We investigate an interacting two-fluid cosmological model and introduce a scalar field representation by means of a linear combination of the individual energy densities. Applying…
Dark energy and dissipation
Diego Pavon, Luis P. Chimento, Alejandro S. Jakubi
Most of the models leading to a current state of cosmic accelerated expansion fail to address the coincidence problem, i.e., that the dark energy density and the energy density of…
Quintessence Energy and Dissipation
Luis P. Chimento, Alejandro S. Jakubi, Diego Pavon
The combined effect of a dissipative fluid and quintessence energy can simultaneously drive an accelerated expansion phase at the present time and solve the coincidence problem of…
