标题： Holographic heat engine efficiency of hyperbolic charged black holes

摘要： 我们考虑一个四维带电的双曲黑洞作为工作物质来建立黑洞全息热机，并使用矩形循环来获得热机效率。 我们发现当熵的增加为零时，双曲黑洞的热机效率变为众所周知的卡诺效率。 我们还发现，在q > 0的情况下，电荷越小效率越高。 此外，我们研究了平坦情况和球面情况的效率，并将这些效率与双曲带电黑洞的效率进行比较。 最后，我们使用数值模拟来研究基准方案中的效率。 显示英文摘要

摘要： 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 q > 0. Furthermore, we study the efficiency of the flat case and spherical case and compare the efficiency with that of the hyperbolic charged black holes. Finally, we use numerical simulation to study the efficiency in benchmark scheme.
