本文综述了近年来有关施温格效应全息描述的研究进展。在2011年，Semenoff和Zarembo提出了一个场景，在AdS/CFT对应的背景下研究Schwinger效应。计算了库仑相中夸克反夸克对的产生率。特别是，它提供了临界值的外电场，超过该值粒子自由创建和真空衰变灾难性。全息方法中的势分析又使我们能够研究限制相的施温格效应。Schwinger效应在约束相的一个显著特征是表现出另一种临界值，低于该临界值，电子对产生不能发生，系统的真空是非微扰稳定的。临界值相当于弦的约束张力。我们计算了对生产率的数值，并介绍了新的指数与临界电场。
This is a review of the recent progress on a holographic description of the Schwinger effect. In 2011, Semenoff and Zarembo proposed a scenario to study the Schwinger effect in the context of the AdS/CFT correspondence. The production rate of quark anti-quark pairs was computed in the Coulomb phase. In particular, it provided the critical value of external electric field, above which particles are freely created and the vacuum decays catastrophically. Then the potential analysis in the holographic approach was invented and it enabled us to study the Schwinger effect in the confining phase as well. A remarkable feature of the Schwinger effect in the confining phase is to exhibit another kind of the critical value, below which the pair production cannot occur and the vacuum of the system is non-perturbatively stable. The critical value is tantamount to the confining string tension. We computed the pair production rate numerically and introduced new exponents associated with the critical electric fields.
