Inflaton Field and Bounce Models
In traditional inflation, there is a field known as the inflaton which a boson of the same name. Hybrid models of inflation , if I've understood correrctly(?) have a field to start inflation and a field to stop it. However recent work on bounce mdoels such as in LQC has argued inflation arises as a consequence of the bounce. Do bounce cosmsologies have anything to say about the nature of the inflaton field. Do we still need to invoke such a field and its boson or is it superflouous in these mdoels?
