经典电子半径下的Abraham-洛伦兹力与电动力学

The Abraham-Lorentz force and electrodynamics at the classical electron radius

Janos Polonyi

摘要:

亚伯拉罕-洛伦兹力是点电荷与其自身场的自相互作用的UV奇异结构的有限余项。这种相互作用的满意的描述需要一个相对论调节器。这是一个有问题的观点,因为受调节的相对论性截止理论的能量是从下面无界的。然而,人们可以构造点分裂调节器,使亚伯拉罕-洛伦兹力保持稳定。通过指出电荷的有效量子理论支持产生经典辐射反作用力的鞍点,经典语言可以与QED调和。

英文摘要:

The Abraham-Lorentz force is a finite remnant of the UV singular structure of the self interaction of a point charge with its own field. The satisfactory description of such interaction needs a relativistic regulator. This turns out to be a problematic point because the energy of regulated relativistic cutoff theories is unbounded from below. However one can construct point splitting regulators which keep the Abraham-Lorentz force stable. The classical language can be reconciled with QED by pointing out that the effective quantum theory for the electric charge supports a saddle point producing the classical radiation reaction forces.
