A class of inflation models with non-minimal coupling

TL;DR

This paper explores a class of inflation models with non-minimal coupling, demonstrating that the scalar field potential becomes flat under certain conditions, which has significant implications for cosmological inflation theories.

Contribution

It introduces a specific condition on non-minimal coupling that ensures a flat potential in the Einstein frame, advancing the understanding of inflationary model construction.

Findings

Potential becomes flat at large field values under the specified condition.

The model's cosmological implications are analyzed.

Provides a new criterion for non-minimal coupling in inflation models.

Abstract

We show that the potential of the scalar field in the Einstein frame is flat if the nonminimal coupling term is properly chosen that it satisfies the condition (V(phi)/K^2(phi)-> constant) as phi gets large. The cosmological implication of this theory is studied.
