- Title
QUINTESSENTIAL INFLATION WITHOUT A POTENTIAL.
- Authors
González-Díaz, Pedro F.
- Abstract
Based on recently proposed unified models for dark matter and energy which are constructed by introducing a generalized Chaplygin vacuum fluid, we suggest in this paper a new scenario for quintessential inflation which does not rely on the existence of a specific potential for the vacuum field, but on a generalization of the definition of the Hilbert–Einstein action for a massless scalar field conformally-coupled to gravity that contains an extra Lagrangian term for the generalized vacuum Chaplygin fluid and the corresponding new surface term.
