Oscillatory inflation in non-minimal derivative coupling model

TL;DR

This paper explores inflation driven by rapid oscillations of a scalar field within a non-minimal derivative coupling framework, analyzing perturbations and their compatibility with Planck 2013 observational data.

Contribution

It introduces a novel inflationary scenario based on oscillations in a non-minimal derivative coupling model and assesses its observational viability.

Findings

Cosmological perturbations are consistent with Planck 2013 data.

Oscillatory inflation can produce observable signatures compatible with current constraints.

The model offers an alternative inflation mechanism with distinct dynamical features.

Abstract

Inflation during rapid oscillation of a scalar field in non-minimal derivative coupling model is discussed. Cosmological perturbations originated in this stage are studied and consistency of the results with observational constraints coming from Planck 2013 data are investigated.
