The GEMS Approach to Stationary Motions in the Spherically Symmetric Spacetimes

TL;DR

This paper extends the theoretical framework for describing Hawking radiation and the Unruh effect in spherically symmetric black holes, unifying these phenomena for general stationary motions and matching thermal spectra.

Contribution

It generalizes previous work to include all stationary motions in spherically symmetric black holes and aligns the chemical potential terms of the thermal spectra.

Findings

Unified description of Hawking radiation and Unruh effect for stationary motions

Matching chemical potential terms in thermal spectra for uncharged black holes

Extension of Deser and Levin's framework to more general scenarios

Abstract

We generalize the work of Deser and Levin on the unified description of Hawking radiation and Unruh effect to general stationary motions in spherically symmetric black holes. We have also matched the chemical potential term of the thermal spectrum of the two sides for uncharged black holes.
