Dark matter-dark energy interaction for a time-dependent equation of state

Rafael C. Nunes, Edésio M. Barboza

In this work we investigate the interaction between dark matter and dark energy for a coupling that obeys the Wang-Meng decaying law, $ρ_{DM} \propto (1 + z)^{3 - ε}$ , and the Barbo…

Dark energy models through nonextensive Tsallis' statistics

Rafael da C. Nunes, Edésio M. Barboza, Everton M. C. Abreu +1

The accelerated expansion of the Universe is one of the greatest challenges of modern physics. One candidate to explain this phenomenon is a new field called dark energy. In this w…
