Vacuum polarization from confined fermions in 3 + 1 dimensions

C. Ccapa Ttira, C. D. Fosco, E. Losada

摘要:

本文研究了平板中无质量旋量QED 4的单圈真空极化函数的主要性质,即场定义在R^(3+1)中的M上,使得M = {(x 0,.,x3)|0 <= x3 <= x4},边界上有袋状边界条件。我们评估的感应电荷密度和电流,由于外部恒定的电场正常的边界,我们还研究了一个纯粹的横向场的有效行动,确定其依赖于ε的贡献。

英文摘要:

We study the main properties of the one-loop vacuum polarization function for massless spinor QED4 in a slab, namely, with fields defined on M in R^(3+1), such that M = {(x0, ..., x3)|0 <= x3 <= epsilon}, and bag-like boundary conditions on the boundary. We evaluate the induced charge density and current due to an external constant electric field normal to the boundary; we also study the effective action for a purely transverse field, identifying its epsilon-dependent contribution.
