Synergistic warm inflation
Luis P. Chimento, Alejandro S. Jakubi, Diego Pavón +1
We consider an alternative warm inflationary scenario in which scalar fields coupled to a dissipative matter fluid cooperate to produce power--law inflation. The scalar fields…
Interacting Quintessence
Winfried Zimdahl, Diego Pavón, Luis P. Chimento
We demonstrate that a suitable coupling between a quintessence scalar field and a pressureless cold dark matter (CDM) fluid leads to a constant ratio of the energy densities of bot…
Cosmic evolution during primordial black hole evaporation
Winfried Zimdahl, Diego Pavón
Primordial black holes with a narrow mass range are regarded as a nonrelativistic fluid component with an equation of state for dust. The impact of the black hole evaporation on th…
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…
