Dark energy from cosmological fluids obeying a Shan-Chen non-ideal equation of state
Donato Bini, Andrea Geralico, Daniele Gregoris +1
We consider a Friedmann-Robertson-Walker universe with a fluid source obeying a non-ideal equation of state with "asymptotic freedom," namely ideal gas behavior (pressure changes d…

Friction forces in cosmological models
Donato Bini, Andrea Geralico, Daniele Gregoris +1
We investigate the dynamics of test particles undergoing friction forces in a Friedmann-Robertson-Walker (FRW) spacetime. The interaction with the background fluid is modeled by in…
