兰姆位移的解析计算方法

Techniques in Analytic Lamb Shift Calculations

U. D. Jentschura

摘要:

量子电动力学是第一个从正则化和重整化的思想中出现的理论,以及费米子与电磁场虚激发的耦合。今天,束缚态量子电动力学为我们提供了与简单原子系统相关的跃迁能量的准确理论预测,稳定的理论进展依赖于计算技术和数值算法的进步。在这篇简短的综述中,我们讨论了与最近的进展有关的一个特殊方面:对低核电荷数的类氢离子的单圈束缚态自能的相对论修正的估算,对于激发的非S态,直到以电子质量为单位的α(Z α)^[6]量级。本文讨论了以前文献中报道的一些计算细节,并给出了6F、7F、6G和7G态的计算结果。

英文摘要:

Quantum electrodynamics has been the first theory to emerge from the ideas of regularization and renormalization, and the coupling of the fermions to the virtual excitations of the electromagnetic field. Today, bound-state quantum electrodynamics provides us with accurate theoretical predictions for the transition energies relevant to simple atomic systems, and steady theoretical progress relies on advances in calculational techniques, as well as numerical algorithms. In this brief review, we discuss one particular aspect connected with the recent progress: the evaluation of relativistic corrections to the one-loop bound-state self-energy in a hydrogenlike ion of low nuclear charge number, for excited non-S states, up to the order of alpha (Zalpha)^6 in units of the electron mass. A few details of calculations formerly reported in the literature are discussed, and results for 6F, 7F, 6G and 7G states are given.
