论文摘要
在本文中，正在使用Penrose过程来从常规黑洞中提取旋转能量。最初，我们考虑旋转的Simpson-Visser常规时空，该时期描述了Kerr Black Hole的模仿者的几何形状类别。然后，通过共同转化的旋转单数和常规黑洞解决方案研究penrose过程。这些simpson-visser和形式转化的几何形状都取决于质量，旋转和附加的正则化参数$ l $。在这两种情况下，我们都会研究自旋和正则化参数$ l $如何影响奇异和事件范围的配置。令人惊讶的是，我们发现事件范围表面的能量提取效率不取决于Simpson-Visser常规空位中的正则化参数$ l $，因此它与Kerr Black Black all case不会有所不同。而在共形的单数和常规黑洞中，与Kerr黑洞方案相比，我们获得的提取能的效率非常高。共形的奇异和常规黑洞的这种独特的标志对于将它们与观察中的Kerr黑洞区分开来是有用的。
In this paper, the Penrose process is being used to extract rotational energy from regular black holes. Initially, we consider the rotating Simpson-Visser regular spacetime which describes the class of geometries of the Kerr black hole's mimickers. The Penrose process is then studied through conformally transformed rotating singular and regular black hole solutions. These both Simpson-Visser and conformally transformed geometries depend on mass, spin, and an additional regularisation parameter $l$. In both cases, we investigate how the spin and regularisation parameter $l$ affects the configuration of an ergoregion and event horizons. Surprisingly, we find that the energy extraction efficiency from the event horizon surface is not dependent on the regularisation parameter $l$ in the Simpson-Visser regular spacetimes and hence it does not vary from the Kerr black hole case. While, in the conformally transformed singular and regular black holes, we obtain the efficiency rate of extracted energies are extremely high compared to the Kerr black hole scenario. This distinct signature of the conformally transformed singular and regular black holes would be useful to distinguish them from the Kerr black hole in observation.
