论文摘要
在能量条件对常规黑洞的重要性的前提下，我们提出了一种方法来纠正破坏主要能量条件的模型，例如Bardeen和Hayward黑洞。我们修改指标，但同时确保其规律性，以便满足弱，无效和主导的能量条件，但强有力的能量条件除外。同样，我们证明了一个无关定理，用于共同相关的常规黑洞，该孔在这类黑洞中永远无法满足四种能量条件。为了寻求将常规黑洞与奇异黑洞区分开的证据，我们诉诸于模拟重力，并将其视为模仿液体中的逼真的常规黑洞的工具。流体的状态方程是通过与数值方法相关的渐近分析来求解的，该方法为实验观察提供了一种方法，尤其是可以模拟流体中现实的常规黑洞的条件。
On the premise of the importance of energy conditions for regular black holes, we propose a method to remedy those models that break the dominant energy condition, e.g., the Bardeen and Hayward black holes. We modify the metrics but ensure their regularity at the same time, so that the weak, null, and dominant energy conditions are satisfied, with the exception of the strong energy condition. Likewise, we prove a no-go theorem for conformally related regular black holes, which states that the four energy conditions can never be met in this class of black holes. In order to seek evidences for distinguishing regular black holes from singular black holes, we resort to analogue gravity and regard it as a tool to mimic realistic regular black holes in a fluid. The equations of state for the fluid are solved via an asymptotic analysis associated with a numerical method, which provides a modus operandi for experimental observations, in particular, the conditions under which one can simulate realistic regular black holes in the fluid.
