Inflection Point Inflation and Time Dependent Potentials in String Theory

TL;DR

This paper explores string theory models of inflection point inflation, demonstrating that they are common and naturally address the overshoot problem by reducing the need for fine-tuned initial conditions.

Contribution

It shows that string theory realizations of inflection point inflation are prevalent and provide a natural solution to the overshoot problem.

Findings

Stringy realizations of inflection point inflation are common.

These models naturally resolve the overshoot problem.

Initial condition fine-tuning is reduced in string theory scenarios.

Abstract

We consider models of inflection point inflation. The main drawback of such models is that they suffer from the overshoot problem. Namely the initial condition should be fine tuned to be near the inflection point for the universe to inflate. We show that stringy realizations of inflection point inflation are common and offer a natural resolution to the overshoot problem.
