Comment on "Anomalous temperature dependence of the Casimir force for thin metal films" [arXiv:0712.1395]
摘要：
最近，A。Yampol'skii，S. Savel'ev，Z. A. Mayselis，S. S. Apostolov和F.海苔[Phys. Rev. Lett.，101，096803（2008），arXiv：0712.1395]声称，由Drude模型描述的薄金属膜和理想金属半空间之间的Casimir力可以随温度降低，而对于体样品，Casimir力随温度增加。在此基础上，提出了薄膜与块状理想金属之间Casimir力大小随温度变化的实验观测结果。我们表明，与作者所声称的相反，Casimir力的大小随温度的降低在一个宽的温度区域的散装样品所描述的德鲁德模型。这种减少被证明是远远大于一个薄膜，它已经被实验排除。
英文摘要：
Recently V. A. Yampol'skii, S. Savel'ev, Z. A. Mayselis, S. S. Apostolov, and F. Nori [Phys. Rev. Lett., v.101, 096803 (2008),arXiv:0712.1395] claimed that the Casimir force between a thin metal film described by the Drude model and an ideal metal semispace can decrease with temperature whereas for bulk samples the Casimir force increases with temperature. On this basis the experimental observation of the decreasing temperature dependence of the Casimir force magnitude between a film and a bulk ideal metal was proposed. We demonstrate that, contrary to what is claimed by the authors, the magnitude of the Casimir force decreases with temperature in a wide temperature region for bulk samples described by the Drude model. This decrease is shown to be much larger than that for a thin film and it has already been experimentally excluded.
