Abstract:The potential V (φ) = λφ n is responsible for the inflation of the universe as scalar field φ oscillates quickly around some point where V (φ) has a minimum. The end of this stage has an important role on the further evolution stages of the universe. The created particles are responsible for reheating the universe at the end of this stage. The behaviour of the inflation and reheating stages are often known as power law expansion S(η) ∝ η 1+β , S(η) ∝ η 1+βs respectively. The reheating temperature (T rh ) and β… Show more
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
