Reflection from black holes and space-time topology

TL;DR

This paper explores how quantum corrections enable black holes to reflect particles at the event horizon, linking this phenomenon to Hawking radiation and the quantum nature of space-time topology.

Contribution

It introduces the concept that quantum effects cause black holes to reflect particles, connecting this to Hawking radiation and the quantum properties of the event horizon.

Findings

Black holes can reflect particles due to quantum corrections.

Reflection probability depends on black hole temperature.

Reflection and Hawking radiation share a common quantum origin.

Abstract

The quantum corrections make the black hole capable of reflection: any particle that approaches the event horizon can bounce back in the outside world. The albedo of the black hole depends on its temperature. The reflection shares physical origins with the phenomenon of Hawking radiation; both effects are explained as consequences of the singular nature that the event horizon exhibits on the quantum level.
