经典电动力学中辐射反作用力的有限尺寸修正

Finite size corrections to the radiation reaction force in classical electrodynamics

Chad R. Galley, Adam K. Leibovich, Ira Z. Rothstein

摘要:

我们介绍了一个有效场论的方法,描述了运动的有限大小的物体的电磁场的影响下。我们证明,由于有限半径$R$的球对称电荷的领先顺序的影响是为了$R^2$,而不是为了$R$在任何物理模型,广泛声称在文献中。这种标度是庞加莱和规范对称性的结果,它们可以排除线性修正。我们利用该方法计算了Abraham-Lorentz-Dirac力的首阶有限尺寸修正。

英文摘要:

We introduce an effective field theory approach that describes the motion of finite size objects under the influence of electromagnetic fields. We prove that leading order effects due to the finite radius $R$ of a spherically symmetric charge is order $R^2$ rather than order $R$ in any physical model, as widely claimed in the literature. This scaling arises as a consequence of Poincaré and gauge symmetries, which can be shown to exclude linear corrections. We use the formalism to calculate the leading order finite size correction to the Abraham-Lorentz-Dirac force.
