无限大平行导体板间非简并能级系统的兰姆位移

Lamb shift of non-degenerate energy level systems placed between two infinite parallel conducting plates

B. Billaud, T. -T. Truong

摘要:

对非简并能级系统中兰姆位移的可观测性问题提出了质疑。为此,我们计算的Lamb位移的电磁环境中提供的两个无限平行的导电板,这是有助于证明存在所谓的Casimir效应的系统。给出了球形半导体量子点兰姆位移相对变化的计算公式。这是一个仔细的数学处理的分歧,在涉及分布理论的计算,这也解决了争议,在现有的文献中的两个不同的表达式。这为量子点非简并能谱的精细调谐提供了可能性,也为Gedanken实验观察球形半导体量子点中的兰姆位移提供了可能性。

英文摘要:

The issue of the observability of the Lamb shift in systems with non-degenerate energy levels is put to question. To this end, we compute the Lamb shift of such systems in the electromagnetic environment provided by two infinite parallel conducting plates, which is instrumental in demonstrating the existence of the so-called Casimir effect. A formula giving the relative change in the Lamb shift (as compared to the standard one in vacuum) is explicitly obtained for spherical semiconductor Quantum Dots (QD). It is the result of a careful mathematical treatment of divergences in the calculations involving distribution theory, which also settles a controversy on two different expressions in the existing literature. It suggests a possibility of QD non-degenerate energy spectrum fine-tuning for experimental purposes as well as a Gedankenexperiment to observe the Lamb shift in spherical semiconductor quantum dots.
