论文摘要
我们将Arxiv：1812.08785引入的Schwinger-keldysh全息施氏施式处方扩展到带电的黑麸皮，以期在这些背景下研究鹰辐射。同等地，我们研究在有限温度和有限化学势下保持的双CFT的实时波动。我们使用带电的Dirac探针字段检查处方。我们在边界衍生物扩展中求解了DIRAC方程，该方程扩展了ARXIV的结果：2011.07039。使用此处方得出的Schwinger-Keldysh相关器会自动满足与费米 - 迪拉克因子的适当KMS关系。
We extend the holographic Schwinger-Keldysh prescription introduced in arXiv:1812.08785 to charged black branes, with a view towards studying Hawking radiation in these backgrounds. Equivalently we study real-time fluctuations of the dual CFT held at finite temperature and finite chemical potential. We check our prescription using charged Dirac probe fields. We solve the Dirac equation in a boundary derivative expansion extending the results in arXiv:2011.07039. The Schwinger-Keldysh correlators derived using this prescription automatically satisfy the appropriate KMS relations with Fermi-Dirac factors.
