关于PFA的精确性:Casimir力和静电力之间的类比

On the accuracy of the PFA: analogies between Casimir and electrostatic forces

Francisco D. Mazzitelli, Fernando C. Lombardo, Paula I. Villar

摘要:

我们提出了一个概述的邻近力近似(PFA)的有效性在计算卡西米尔力之间的完美导体为不同的几何形状,特别强调在一个平面前的圆柱体的配置。在所有情况下,我们比较精确的数值结果与PFA的,并与渐近展开,包括下一个领导阶校正。我们还讨论了卡西米尔和静电力的结果之间的异同。

英文摘要:

We present an overview of the validity of the Proximity Force Approximation (PFA) in the calculation of Casimir forces between perfect conductors for different geometries, with particular emphasis for the configuration of a cylinder in front of a plane. In all cases we compare the exact numerical results with those of PFA, and with asymptotic expansions that include the next to leading order corrections. We also discuss the similarities and differences between the results for Casimir and electrostatic forces.
