波纹金属板间的真空感应扭矩

Vacuum induced torque between corrugated metallic plates

Robson B. Rodrigues, Paulo A. Maia Neto, A. Lambrecht, S. Reynaud

摘要:

研究了两波纹金属板与电磁真空相互作用时产生的力矩。该Casimir扭矩可以用扭摆技术测量,用于大至1 $μ$ m的分离距离。它允许一个探测的非平凡的几何形状依赖的卡西米尔能量的配置,可以在理论上进行评估的准确性。在最佳实验配置中,通常使用的接近力近似结果高估了扭矩的2倍或更大。

英文摘要:

We study the torque arising between two corrugated metallic plates due to the interaction with electromagnetic vacuum. This Casimir torque can be measured with torsion pendulum techniques for separation distances as large as 1$μ$m. It allows one to probe the nontrivial geometry dependence of the Casimir energy in a configuration which can be evaluated theoretically with accuracy. In the optimal experimental configuration, the commonly used proximity force approximation turns out to overestimate the torque by a factor 2 or larger.
