The Hawking effect in the particles-partners correlations

TL;DR

This paper investigates the correlations between Hawking particles and their partners across black hole horizons, examining how different spacetime backgrounds influence these correlations in various black hole models.

Contribution

It provides a comparative analysis of particle-partner correlations in different black hole spacetimes, including acoustic and regular black holes.

Findings

Correlations are affected by the spacetime geometry.

Hawking particles are entangled with their partners across the horizon.

Different black hole models show distinct correlation patterns.

Abstract

We analyze the correlations functions across the horizon in Hawking black hole radiation to reveal the correlations between Hawking particles and their partners. The effects of the underlying space-time on this are shown in various examples ranging from acoustic black holes to regular black holes.
