近极值RN黑洞中Schwinger效应的热解释

Thermal Interpretation of Schwinger Effect in Near-Extremal RN Black Hole

Sang Pyo Kim, Hyun Kyu Lee, Yongsung Yoon

摘要:

提出了极端和近极端Reissner-Nordström(RN)黑洞中带电标量和旋量Schwinger效应的热解释。电荷的发射具有这样的分布,其有效温度由电场加速电荷的Davies-Unruh温度和AdS_2的标量曲率决定,来自近视界几何结构AdS_2 × S^2。我们发现一个电荷约束的极端微型黑洞保持稳定的Schwinger发射类比Breitenlohlner-Freedman约束的AdS空间。在in-out形式中,我们发现单圈QED有效作用量与真空持久性一致,并将真空持久性解释为主导的Schwinger效应和库仑场的荷电真空效应。

英文摘要:

We propose a thermal interpretation of the Schwinger effect for charged scalars and spinors in an extremal and near-extremal Reissner-Nordström (RN) black hole. The emission of charges has the distribution with an effective temperature determined by the Davies-Unruh temperature for accelerating charges by the electric field and the scalar curvature of AdS_2 from the near-horizon geometry AdS_2 X S^2. We find a charge bound for the extremal micro black hole to remain stable against the Schwinger emission in analogy with the Breitenlohlner-Freedman bound for the AdS space. In the in-out formalism we find the one-loop QED effective action consistent with the vacuum persistence and interpret the vacuum persistence as the leading Schwinger effect and the effect of a charged vacuum of the Coulomb field.
