Abstract
Using a recently developed theory of the Casimir force (Raabe and Welsch 2005 Phys. Rev. A 71 013814), we calculate the force that acts on a plate in front of a planar wall and the force that acts on the plate in the case where the plate is part of matter that fills the space in front of the wall. We show that in the limit of a dielectric plate whose permittivity is close to unity, the force obtained in the former case reduces to the ordinary, i.e., unscreened, Casimir–Polder force acting on isolated atoms. In the latter case, the theory yields the Casimir–Polder force that is screened by the surrounding matter.
利用最近发展的卡西米尔力理论(Raabe and Welsch, 2005)。Rev. A 71 013814),我们计算了作用在平面墙前面的板上的力,以及作用在板上的力,当板是填充墙前面空间的物质的一部分时。我们证明,在介电常数接近于单位的介电板的极限下,在前一种情况下得到的力减小到普通的,即未屏蔽的,卡西米尔-波尔德力作用在孤立的原子上。在后一种情况下,该理论产生被周围物质屏蔽的卡西米尔-波尔德力。
