Quintessential Inflation in Mimetic Dark Matter

Understand

A quintessential Inflation (QI) scenario from Mimetic Dark Matter (MDM) is presented in this paper.

• This scenario, which is based on the MDM model presented by Chamseddine and Mukhanov \cite{chams}, uses a potential that is defined on three time intervals:the first during inflation, the second $10^{-65}s$ after the end of inflation and the third after that.
• The resulting energy density of the universe is constant during inflation, followed by that of a matter/radiation dominated universe, and finally ends with a constant energy density corresponding to dark energy.
• The scale factor has an accelerating expansion nature during and after inflation.
