Charged Unruh effect on geon spacetimes

TL;DR

This paper explores how topological geon black holes with gauge charges influence the Unruh effect, revealing non-thermal correlations for same-charge particle pairs due to charge conjugation gauge symmetry.

Contribution

It demonstrates that gauging charge conjugation in geon spacetimes affects the Unruh effect, producing observable non-thermal correlations for same-charge particles.

Findings

Non-thermal correlations for same-charge pairs in geon spacetimes

Charge conjugation gauge symmetry impacts the Unruh effect

Similar phenomena observed in Rindler spacetimes with gauge fields

Abstract

A topological geon black hole with gauge charges may have a gauge bundle that necessarily incorporates charge conjugation as a gauge symmetry. This happens for example for the Reissner-Nordstrom geon. We show that gauging the charge conjugation leaves an imprint in the Unruh effect: the geon's exterior region contains non-thermal correlations for particle pairs of the same, rather than opposite, charge. The phenomenon occurs also in topologically similar Rindler spacetimes with a background gauge field.
