# Holographic Heat Engine Efficiency of Hyperbolic Charged Black Holes

@article{Sun2021HolographicHE, title={Holographic Heat Engine Efficiency of Hyperbolic Charged Black Holes}, author={Wei Sun and Xian-hui Ge}, journal={Chinese Physics B}, year={2021} }

We consider a four-dimensional charged hyperbolic black hole as working matter to establish a black hole holographic heat engine, and use the rectangular cycle to obtain the heat engine efficiency. We find that when the increasing of entropy is zero, the heat engine efficiency of the hyperbolic black hole becomes the well-known Carnot efficiency. We also find that less charge corresponds to higher efficiency in the case of Λ π > 0. Furthermore, we study the efficiency of the flat case andβ¦Β
