TL;DR
This paper investigates the quantum creation of topological black holes using the constrained instanton method, revealing that the creation probability at the WKB level depends exponentially on the sum of horizon areas.
Contribution
It introduces a method to compute the quantum creation probability of topological black holes based on horizon areas using the constrained instanton approach.
Findings
Creation probability is exponential of quarter sum of horizon areas.
The method applies to vacuum and charged topological black holes.
Provides a new perspective on black hole nucleation in quantum gravity.
Abstract
The constrained instanton method is used to study quantum creation of a vacuum or charged topological black hole. At the level, the relative creation probability is the exponential of a quarter sum of the horizon areas associated with the seed instanton.
