TL;DR
This paper constructs exact solutions for electrically charged phantom black holes with a cosmological constant, revealing that phantom fields significantly influence black hole properties and uphold the third law of thermodynamics.
Contribution
It introduces new exact solutions for phantom black holes with charge and cosmological constant, analyzing their thermodynamic and cosmological implications.
Findings
Extremal charged phantom black holes cannot be achieved.
Phantom fields alter black hole properties.
The third law of thermodynamics remains valid for these black holes.
Abstract
The exact solutions of electrically charged phantom black holes with the cosmological constant are constructed. They are labelled by the mass, the electrical charge, the cosmological constant and the coupling constant between the phantom and the Maxwell field. It is found that the phantom has important consequences on the properties of black holes. In particular, the extremal charged phantom black holes can never be achieved and so the third law of thermodynamics for black holes still holds. The cosmological aspects of the phantom black hole and phantom field are also briefly discussed.
