Inflaton field fluctuations from gauge-invariant metric fluctuations during inflation

The evolution of the inflaton field fluctuations from gauge-invariant metric fluctuations is discused. In particular, the case of a symmetric $ϕ_c$-exponential potential is analyzed.

Metric fluctuations and its evolution during inflation

W discuss the evolution of the fluctuations in a symmetric $ϕ_c$-exponential potential which provides a power-law expansion during inflation using both, the gauge invariant field $Φ$ and the Sasaki-Mukhanov field.
