真实金属间热Casimir力的新探讨

New approach to the thermal Casimir force between real metals

V. M. Mostepanenko, B. Geyer

摘要:

提出了一种新的理论描述实际金属间热Casimir力的方法。它使用的等离子体类的介电常数,考虑到核心电子的带间跃迁。该介电常数精确地满足Kramers-Kronig关系。根据能斯特热定理,相应的卡西米尔熵是正的,并且在零温度下为零。阐明了在Lifshitz公式中代入Drude介电函数与电动力学不一致的物理原因。所提出的方法是唯一一个与迄今为止进行的卡西米尔力的所有测量相一致的方法。这种方法的应用被认为是金属型半导体。

英文摘要:

The new approach to the theoretical description of the thermal Casimir force between real metals is presented. It uses the plasma-like dielectric permittivity that takes into account the interband transitions of core electrons. This permittivity precisely satisfies the Kramers-Kronig relations. The respective Casimir entropy is positive and vanishes at zero temperature in accordance with the Nernst heat theorem. The physical reasons why the Drude dielectric function, when substituted in the Lifshitz formula, is inconsistent with electrodynamics are elucidated. The proposed approach is the single one consistent with all measurements of the Casimir force performed up to date. The application of this approach to metal-type semiconductors is considered.
