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…

Phantom cosmologies and fermions
Luis P. Chimento, Fernando P. Devecchi, Monica Forte +1
Form invariance transformations can be used for constructing phantom cosmologies starting with conventional cosmological models. In this work we reconsider the scalar field case an…

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…
