在最近的一篇论文[1]中，Kundu和本文作者之一证明了，如果麦克斯韦场的拉格朗日量包含CP破坏角θ，则在黑洞视界上经典电流的衰变中存在瞬态但可观测的CP破坏效应。在本文中，我们证明了一个类似的效果，可以看到在量子力学的QED：一个非平凡的Berry相位的QED波函数是由落在电荷。我们还调查是否CP违反，这种或任何其他类型的，可能会被用来产生重子不对称的宇宙，在模型中，原始黑洞衰变有助于本宇宙的物质含量。这可以发生在各种混合暴胀模型和全息时空（HST）暴胀模型中[2]。
In a recent paper[1] Kundu and one of the present authors showed that there were transient but observable CP violating effects in the decay of classical currents on the horizon of a black hole, if the Lagrangian of the Maxwell field contained a CP violating angle �. In this paper we demonstrate that a similar effect can be seen in the quantum mechanics of QED: a non-trivial Berry phase in the QED wave function is produced by in-falling electric charges. We also investigate whether CP violation, of this or any other type, might be used to produce the baryon asymmetry of the universe, in models where primordial black hole decay contributes to the matter content of the present universe. This can happen both in a variety of hybrid inflation models, and in the Holographic Space-time (HST) model of inflation[2].
