论文摘要
超高被称为由旋转或带电的黑洞引起的波浪扩增过程。我们认为，在渐近广告空间中固定黑洞的超沉淀可以以能量提取的能力为特征。具体而言，我们证明可以从Reissner-Nordström-Ads $ _4 $和KERR-ADS $ _4 $中提取能量，该能量在相关边界的适当时间依赖性边界条件下。这表明可以通过施加适当的时间依赖性来源从热状态从热状态提取能量。我们还表明，能量提取可以实现为可逆过程。
Superradiance is known as a wave amplification process caused by rotating or charged black holes. We argue that the superradiance of stationary black holes in asymptotically AdS spacetimes can be characterized by the ability of energy extraction. Specifically, we demonstrate that energy can be extracted from Reissner-Nordström-AdS$_4$ and Kerr-AdS$_4$ under appropriate time-dependent boundary conditions at conformal boundaries. This indicates that energy can be extracted from thermal states dual to these black holes by applying appropriate time-dependent sources. We also show that the energy extraction can be realized as a reversible process.
