液体中的排斥和吸引Casimir相互作用
Repulsive and attractive Casimir interactions in liquids
摘要：
用Lifshitz理论研究了固-液-固体系中Casimir相互作用随分离距离的变化。介电常数函数的范围很广的材料描述的德鲁德，德鲁德-洛伦兹和振荡器模型。我们发现金与二氧化硅或MgO材料之间的Casimir力既有排斥力又有吸引力。我们还找到了系统的稳定形式。本文的研究结果对今后色散相互作用的实验研究具有一定的指导意义。
英文摘要：
The Casimir interactions in the solid-liquid-solid systems as a function of separation distance have been studied by the Lifshitz theory. The dielectric permittivity functions for a wide range of materials are described by Drude, Drude-Lorentz and oscillator models. We find that the Casimir forces between gold and silica or MgO materials are both the repulsive and attractive. We also find the stable forms for the systems. Our studies would provide a good guidance for the future experimental studies on the dispersion interactions.
