Entropy of Kerr--Newman--AdS black holes with torsion

TL;DR

This paper extends the canonical approach to black hole entropy in Poincaré gauge theory to include Maxwell fields, calculating the entropy and charges of Kerr--Newman--AdS black holes with torsion, showing the first law remains consistent.

Contribution

It introduces a formalism for black hole entropy in Poincaré gauge theory with Maxwell fields, maintaining the first law's form.

Findings

Entropy calculation for Kerr--Newman--AdS black holes with torsion

First law of black hole thermodynamics holds with Maxwell contribution

Formalism aligns with general relativity results

Abstract

The canonical approach to black hole entropy in Poincar\'e gauge theory without matter is extended to include Maxwell field as a matter source. The new formalism is used to calculate asymptotic charges and entropy of Kerr--Newmann--AdS black holes with torsion. The result implies that the first law, with a nontrivial contribution of the Maxwell field, takes the same form as in general relativity.
