Getting inflationary models using the deformation method

TL;DR

This paper introduces a deformation method to analyze slow-roll inflation models, enabling the construction of various inflationary scenarios such as eternal inflation from chaotic inflation.

Contribution

It presents a novel deformation procedure to relate and generate different inflationary potentials in slow-roll models.

Findings

Derived explicit relations between inflationary potentials

Constructed eternal inflation from chaotic inflation

Built natural inflation from hilltop inflation

Abstract

In this paper we show that the dynamics associated with slow-roll models of inflation can be investigated through a method called deformation procedure. Using the latter, we explicitly derive an expression linking two slow-roll inflationary potentials, applying the resulting framework to show how to construct an eternal inflation from chaotic inflation, or even, a natural inflation from hilltop inflation, easily.
