闭几何中的吸引Casimir力

Attractive Casimir Forces in a Closed Geometry

M. P. Hertzberg, R. L. Jaffe, M. Kardar, A. Scardicchio

摘要:

研究了作用在任意截面导电活塞上的Casimir力。我们找到了矩形截面的精确解,以及当截面为任意形状时,小高宽比渐近展开式中的前三项。尽管由于壁的存在而减弱了,卡西米尔力却总是有吸引力的。对于相关的构型,如立方体,排斥卡西米尔力的声明是无效的截止依赖性。

英文摘要:

We study the Casimir force acting on a conducting piston with arbitrary cross section. We find the exact solution for a rectangular cross section and the first three terms in the asymptotic expansion for small height to width ratio when the cross section is arbitrary. Though weakened by the presence of the walls, the Casimir force turns out to be always attractive. Claims of repulsive Casimir forces for related configurations, like the cube, are invalidated by cutoff dependence.
