Bulk Viscous Cosmology
R. Colistete, J. C. Fabris, J. Tossa +1
We propose a scenario in which the dark components of the Universe are manifestations of a single bulk viscous fluid. Using dynamical system methods, a qualitative study of the hom…
Gas models for inflation and quintessence
W. Zimdahl, A. B. Balakin, D. J. Schwarz +1
Specific internal self-interactions in gaseous cosmic fluids are shown to give rise to effective negative pressures which may violate the strong energy condition. On this basis we…
Reheating and causal thermodynamics
Winfried Zimdahl, Diego Pavón, Roy Maartens
The reheating process in inflationary universe models is considered as an out-of-equilibrium mixture of two interacting and reacting fluids, and studied within the framework of cau…
