Alternative Derivation of the Correspondence Between Rindler and Minkowski Particles

TL;DR

This paper offers an alternative derivation of the relationship between Rindler and Minkowski particles, showing that Minkowski particle emission can correspond to either emission or absorption of Rindler particles, enhancing understanding of particle detection in different frames.

Contribution

It provides a novel derivation of the Rindler-Minkowski particle correspondence, including an inverted perspective on emission and absorption processes.

Findings

Minkowski particle emission can correspond to Rindler particle emission or absorption.

The derivation offers a new perspective on the Unruh effect.

Clarifies the particle detection process for accelerated observers.

Abstract

We develop an alternative derivation of Unruh and Wald's seminal result that the absorption of a Rindler particle by a detector as described by uniformly accelerated observers corresponds to the emission of a Minkowski particle as described by inertial observers. Actually, we present it in an inverted version, namely, that the emission of a Minkowski particle corresponds in general to either the emission or the absorption of a Rindler particle.
