论文摘要
我们考虑作用在磁性腔腔内的介电球表面上的相互作用压力。无论在热平衡下系统的腔体的几何形状如何，我们都会确定此数量的符号，从而扩展了dzyaloshinskii-lifshitz-pitaevskii的均匀平衡的结果。与以前关于Casimir-Lifshitz力的定理一样，结果是基于散射形式主义的。在这种情况下，证明是从电磁散射的可变相接种遵循的。因此，我们提出了配置，其中相互作用和对压力的自我能量贡献都倾向于扩大球体。
We consider the interaction pressure acting on the surface of a dielectric sphere enclosed within a magnetodielectric cavity. We determine the sign of this quantity regardless of the geometry of the cavity for systems at thermal equilibrium, extending the Dzyaloshinskii-Lifshitz-Pitaevskii result for homogeneous slabs. As in previous theorems regarding Casimir-Lifshitz forces, the result is based on the scattering formalism. In this case the proof follows from the variable phase approach of electromagnetic scattering. With this, we present configurations in which both the interaction and the self-energy contribution to the pressure tend to expand the sphere.
