Is Emergent Universe a Consequence of Particle Creation Process?
arXiv:1403.5980 · doi:10.1016/j.physletb.2014.03.028
Abstract
A model of an emergent universe is formulated using the mechanism of particle creation. Here the universe is considered as a non-equilibrium thermodynamical system with dissipation due to particle creation mechanism. The universe is chosen as spatially flat FRW space-time and the cosmic substratum is chosen as perfect fluid with barotropic equation of state. Both first and second order deviations from equilibrium prescription is considered and it is found that the scenario of emergent universe is possible in both the cases.
