摘要:

我们已经测量了晶体Ge板之间的短程吸引力,并发现Casimir力和可能由表面补丁电位产生的电力的贡献。使用表面贴片效应的模型,该模型由于表观接触电位的距离依赖性而产生额外的力,使用Casimir力相对较小的距离处的数据对电力进行参数化。外推该模型,以提供在小于5 $μ$ m的距离处的测量力的校正,示出了在实验不确定度内与用于计算卡西米尔力的五个模型一致的残余力。

英文摘要:

We have measured the short-range attractive force between crystalline Ge plates, and found contributions from both the Casimir force and an electrical force possibly generated by surface patch potentials. Using a model of surface patch effects that generates an additional force due to a distance dependence of the apparent contact potential, the electrical force was parameterized using data at distances where the Casimir force is relatively small. Extrapolating this model, to provide a correction to the measured force at distances less than 5 $μ$m, shows a residual force that is in agreement, within experimental uncertainty, with five models that have been used to calculate the Casimir force.
