论文摘要
考虑到抗De Sitter中黑洞的无力电动力学。我们提出了抗De Sitter中无力电动力学的新型能量提取溶液 - 靠近地平线的极端Kerr和超级近距离的超极端Kerr几何形状。相关运动方程是从无力等离子体的动作中得出的，该动作围绕着具有通用渐近造物的黑洞旋转。我们考虑旋转框架中电动力场的能量通量，以指出能量提取的正确度量是通过近距离区域的旋转观察者测量的能量通量。我们通过应用于Kerr，Ads-Kerr和BTZ的近地平线解决方案来说明此过程。
Force-Free Electrodynamics for black holes in Anti de Sitter is considered. We present new, energy extracting solutions of Force-Free Electrodynamics in Anti de Sitter - Near Horizon Extremal Kerr and Super-Entropic Near Horizon Extremal Kerr geometries. The relevant equations of motion are derived from an action for force-free plasma surrounding spinning black holes with generic asymptotics. We consider the energy flux of electrodynamic fields in rotating frames to argue that the correct measure for energy extraction is the energy flux measured by a rotating observer in the near horizon region. We illustrate this procedure by application to near horizon solutions in Kerr, AdS-Kerr and BTZ.
