Unruh Duality and Maximum Acceleration in String Theory

TL;DR

This paper explores a duality interpretation of the Unruh effect within String Theory, revealing a maximum effective acceleration for observers through T-duality, which could have implications for understanding quantum gravity.

Contribution

It introduces a novel connection between the Unruh effect and T-duality in String Theory, identifying a maximum acceleration limit for observers.

Findings

A maximum effective acceleration for observers in String Theory is established.

The Unruh effect can be interpreted as a duality between different backgrounds.

T-duality is used to relate acceleration and background transformations.

Abstract

It is argued that the Unruh effect may be interpreted as a duality of a theory on different backgrounds. This issue is revisited in String Theory in the path integral formalism. By using T-duality and the Unruh effect, the T-dual transformation for acceleration is investigated and a maximum effective physical acceleration for observers in String Theory is found.
