Acceleration radiation and the Planck scale

TL;DR

This paper demonstrates that the Unruh effect, where an accelerating observer perceives a thermal bath, can be derived without relying on high-energy physics, indicating its robustness against Planck-scale modifications.

Contribution

It shows that acceleration radiation can be derived in higher dimensions without invoking Planck-scale physics, supporting its universality and compatibility with microscopic theories.

Findings

Unruh effect derivable without high-energy physics in dimensions > 2

Supports robustness of acceleration radiation against Planck-scale physics

Indicates compatibility with various microscopic theories

Abstract

A uniformly accelerating observer perceives the Minkowski vacuum state as a thermal bath of radiation. We point out that this field-theory effect can be derived, for any dimension higher than two, without actually invoking very high energy physics. This supports the view that this phenomenon is robust against Planck-scale physics and, therefore, should be compatible with any underlying microscopic theory.
