论文摘要

在我们早期的作品中开发的强场QED的非扰动公式之后,并使用石墨烯的狄拉克模型,我们构建了一个还原的Qed_ {3,2}来描述石墨烯中与外部电场和光子相互作用的Dirac Fermions的一种物种。在此基础上,我们考虑该模型中的光子发射,并为总概率构造闭合公式。使用衍生公式,我们研究了电子和光子发射的光子发射概率,以及伴随的光子发射,伴随于准恒定电场中的真空不稳定性,该电场在时间间隔T中作用于石墨烯平面中。我们研究了发射的角度和偏振分布,以及频率和低频率和低频率和低频率的发射特性。我们分析了在实验室条件下提出的计算对石墨烯物理的适用性。实际上,我们正在谈论在这些条件下可能观察到施温格效应。

Following a nonperturbative formulation of strong-field QED developed in our earlier works, and using the Dirac model of the graphene, we construct a reduced QED_{3,2} to describe one species of the Dirac fermions in the graphene interacting with an external electric field and photons. On this base, we consider the photon emission in this model and construct closed formulas for the total probabilities. Using the derived formulas, we study probabilities for the photon emission by an electron and for the photon emission accompanying the vacuum instability in the quasiconstant electric field that acts in the graphene plane during the time interval T. We study angular and polarization distribution of the emission as well as emission characteristics in a high frequency and low frequency approximations. We analyze the applicability of the presented calculations to the graphene physics in laboratory conditions. In fact, we are talking about a possible observation of the Schwinger effect in these conditions.
