近场自相互作用
Self interaction near dielectrics
摘要:
我们计算作用在均匀介质球外的自由静电荷电荷上的力。我们将这种力视为自相互作用力,并通过将洛伦兹力直接应用于电荷所在位置的电场来计算它。我们使用两种不同的方法来正则化发散裸力:直接应用Quinn-Wald比较公理和模态和正则化。
英文摘要:
We compute the force acting on a free, static electric charge outside a uniform dielectric sphere. We view this force as a self-interaction force, and compute it by applying the Lorentz force directly to the charge's electric field at its location. We regularize the divergent bare force using two different methods: A direct application of the Quinn-Wald Comparison Axiom, and Mode-Sum Regularization.
