评“有限宽镜的Casimir能量”

Comment on "Casimir energies with finite-width mirrors"

Ignat Fialkovsky, Yuriy Pis'mak, Vladimir Markov

摘要:

我们对Fosco、Lombardo和Mazzitelli最近发表的一篇关于材料板(“有限宽度反射镜”)的Casimir能量的文章[1]进行了评论,并报告了在那里获得的单个反射镜的结果与以前的一些计算结果之间的差异。我们提供了一个简单的一致性检查,证明了[1]中使用的方法是不可靠的,当应用于近似的分段常数轮廓的反射镜。根据我们最近的工作,我们还提出了一种计算这类系统中Casimir能量的替代方法。我们的结果与微扰理论和一些较老的\cite{Bordag'95}及较新的\cite{Vassilevitch'08}计算相一致,但与[1]的结果不同。

英文摘要:

We comment on a recent publication [1] by Fosco, Lombardo and Mazzitelli on Casimir energies for material slabs (`finite width mirrors') and report a discrepancy between results obtained there for a single mirror and some previous calculations. We provide a simple consistency check which proves that the method used in [1] is not reliable when applied to approximations of piecewise constant profile of the mirror. We also present an alternative method for calculation of the Casimir energy in such systems based on our recent work. Our results coincide both with perturbation theory and with some older \cite{Bordag'95} and more recent \cite{Vassilevitch'08} calculations, but differ from those of [1].
