任意几何形状介质体之间的Lifshitz相互作用

Lifshitz Interaction between Dielectric Bodies of Arbitrary Geometry

Ramin Golestanian

摘要:

本文提出了一种计算任意几何形状的电介质物体在小间距处的电磁涨落力的公式,作为电介质对比度的微扰展开。由此产生的Lifshitz能量自动呈现出不同多体贡献的级数展开形式。该公式的优点是,发散的贡献可以很容易地确定和减去,从而使一个方便的计划,现实的数值计算,这可能是有用的,在设计纳米尺度的机械设备。

英文摘要:

A formulation is developed for the calculation of the electromagnetic--fluctuation forces for dielectric objects of arbitrary geometry at small separations, as a perturbative expansion in the dielectric contrast. The resulting Lifshitz energy automatically takes on the form of a series expansion of the different many-body contributions. The formulation has the advantage that the divergent contributions can be readily determined and subtracted off, and thus makes a convenient scheme for realistic numerical calculations, which could be useful in designing nano-scale mechanical devices.
