Dark Energy Effects on Charged and Rotating Black Holes

TL;DR

This paper investigates how dark energy influences the radiation spectrum, temperature, and information of charged and rotating black holes, revealing that dark energy acts as a cooling agent reducing Hawking radiation.

Contribution

It analytically extends previous work to charged and rotating black holes, demonstrating dark energy's cooling effect on their radiation properties.

Findings

Dark energy causes black holes to emit colder radiation.

Dark energy slows down Hawking radiation.

Results align with previous Schwarzschild black hole studies.

Abstract

Using canonical typicality method, we reconsider the study of dark energy effects on four dimensional black holes. Concretely, we investigate the associated influences on the spectrum of various black hole backgrounds including the charged and the rotating ones. For such black hole solutions, we first elaborate analytically the corresponding radiation spectrum, the Hawking temperature and the dark information. Then, we discuss and analyze the corresponding findings. This work, recovering the results of the Schwarzschield black hole, confirms that dark energy can be considered as a cooling system surrounding the black holes providing a colder radiation and a slower Hawking radiation process.
