How anti-de Sitter black holes reach thermal equilibrium

It is commonly known in the literature that large black holes in anti-de Sitter spacetimes (with reflective boundary condition) are in thermal equilibrium with their Hawking radiation. Focusing on black holes with event horizon of toroidal topology, we study a simple model to understand explicitly how this thermal equilibrium is reached under Hawking evaporation. It is shown that it is possible for a large toroidal black hole to evolve into a small (but stable) one.(C) 2022 The Author(s). Published by Elsevier B.V.

This study focuses on understanding the thermal equilibrium of large black holes with toroidal topology in anti-de Sitter spacetimes through a simple model. It shows that it is possible for a large toroidal black hole to evolve into a small but stable one through Hawking evaporation.
