TL;DR
This paper discusses how multiple axion fields in string theory can naturally facilitate a stable form of chaotic inflation in the early universe.
Contribution
It introduces the concept of N-flation, leveraging many axions to achieve inflation with improved stability and simplicity compared to single-field models.
Findings
Multiple axions can collectively drive inflation effectively.
N-flation offers a radiatively stable inflationary mechanism.
The model aligns with string theory frameworks.
Abstract
The presence of many axion fields in four-dimensional string vacua can lead to a simple, radiatively stable realization of chaotic inflation.
