Abstract

The gyromagnetic ratio and Pauli form factor are important quantities that characterize the electric and magnetic moment distribution of a particle. The experimentally measured value for the gyromagnetic ratio or the spin g-factor of an electron in a vacuum agrees remarkably well with theoretical predictions, making it one of the biggest successes of quantum field theory. However, these factors may get modified compared to their vacuum counterparts due to the interaction present in the system. Motivating from that, in this article, we investigate the effects of interactions within the framework of \(2+1\) dimensional Proca quantum electrodynamics. We demonstrate how the g-factor and Pauli form factors change with the electron’s Fermi velocity and the mass of the vector fields within Proca quantum electrodynamics.

单回路各向异性中回旋磁比和泡利形状因子\(\hbox {QED}_{2 + 1}\)
旋磁比和泡利形状因子是表征粒子电矩和磁矩分布的重要量。真空中电子的回旋磁比或自旋g因子的实验测量值与理论预测非常吻合,使其成为量子场论的最大成功之一。然而,由于系统中存在的相互作用,这些因素可能与真空相比较而得到修改。由此,在本文中,我们研究了\(2+1\)维Proca量子电动力学框架内相互作用的影响。我们演示了g因子和泡利形状因子是如何随着电子的费米速度和Proca量子电动力学中矢量场的质量而变化的。
