A generalized equation of state for dark energy
E. M. Barboza, J. S. Alcaniz, Zong-Hong Zhu +1
A generalized parameterization for the dark energy equation of state (EoS) is proposed and some of its cosmological consequences are investigated. We show that in the limi…

A parametric model for dark energy
E. M. Barboza, J. S. Alcaniz
Determining the mechanism behind the current cosmic acceleration constitutes a major question nowadays in theoretical physics. If the dark energy route is taken, this problem may p…

Does the Big Rip survive quantization?
Edesio M. Barboza, Nivaldo A. Lemos
It is known that certain quantum cosmological models present quantum behavior for large scale factors. Since quantization can suppress past singularities, it is natural to inquire…
