A new phase of scalar field with a kinetic term non-minimally coupled to gravity

Understand

We consider the dynamics of a scalar field non-minimally coupled to gravity in the context of cosmology.

• It is demonstrated that there exists a new phase for the scalar field, in addition to the inflationary and dust-like (reheating period) phases.
• Analytic expressions for the scalar field and the Hubble parameter, which describe the new phase are given.
• The Hubble parameter indicates an accelerating expanding Universe.
