Scalar field inflation and Shan-Chen fluid models
2014 (English)In: Physical Review D, ISSN 1550-7998, Vol. 90, no 4, 044021- p.Article in journal (Refereed) Published
A scalar field equivalent to a nonideal “dark energy fluid” obeying a Shan-Chen-like equation of state is used as the background source of a flat Friedmann-Robertson-Walker cosmological spacetime to describe the inflationary epoch of our Universe. Within the slow-roll approximation, a number of interesting features are presented, including the possibility to fulfill current observational constraints as well as a graceful exit mechanism from the inflationary epoch.
