Inflation-Dark Matter unified through Quantum Generation

Understand

We unify inflation and dark matter via a single scalar field phi.

• One of the main difficulties for this unification is that between inflation and dark matter one needs a successful reheating process and a long lasting period of radiation.
• Therefore the amount of energy density in the inflaton-dark matter field phi must be fine tune after reheating to give dark matter.
• Here we show an alternative scheme in which the inflaton decays completely, disappearing entirely from the spectrum.
