摘要:

两个波纹金属板之间的横向Casimir力使得研究几何形状和Casimir效应之间的非平凡相互作用成为可能,这超出了邻近力近似(PFA)的有效性范围。定量评价可以通过使用散射理论在微扰展开有效时,振幅小于其他三个长度尺度:平均分离距离$L$的板,周期$λ_\C$和等离子体波长$λ_¶$。在这个微扰的扩展,评估获得任意相对值的$L$,$λ_\C$和$λ_¶$,而限制的情况下,其中一些已经知道,恢复时,这些值服从一些特定的排序。这些结果与现有的实验比较的后果进行了讨论,在文章的最后。

英文摘要:

The lateral Casimir force between two corrugated metallic plates makes possible a study of the nontrivial interplay of geometry and Casimir effect appearing beyond the regime of validity of the Proximity Force Approximation (PFA). Quantitative evaluations can be obtained by using scattering theory in a perturbative expansion valid when the corrugation amplitudes are smaller than the three other length scales: the mean separation distance $L$ of the plates, the corrugation period $λ_\C$ and the plasma wavelength $λ_¶$. Within this perturbative expansion, evaluations are obtained for arbitrary relative values of $L$, $λ_\C$ and $λ_¶$ while limiting cases, some of them already known, are recovered when these values obey some specific orderings. The consequence of these results for comparison with existing experiments is discussed in the end of the paper.
