Casimir弹簧和指南针：紧凑物体的稳定悬浮和对准
Casimir spring and compass: Stable levitation and alignment of compact objects
摘要：
我们研究了一个稳定的卡西米尔力配置包含一个包含在一个球形或椭球形的空腔充满电介质的对象。计算了腔体中心位移的弹性常数和能量对内部物体和腔壁相对取向的依赖性。我们发现力平衡的稳定性可以根据力的符号来预测，但扭矩不能。
英文摘要：
We investigate a stable Casimir force configuration consisting of an object contained inside a spherical or spheroidal cavity filled with a dielectric medium. The spring constant for displacements from the center of the cavity and the dependence of the energy on the relative orientations of the inner object and the cavity walls are computed. We find that the stability of the force equilibrium can be predicted based on the sign of the force, but the torque cannot be.
