Repulsive Casimir force between silicon dioxide and superconductor

We have presented a detailed investigation of the Casimir interaction between the superconductor Bi2Sr2CaCu2O8+δ (BSCCO) and silicon dioxide with the presence of bromobenzene in between. We found the dispersion force is repulsive and the magnitude of the force can be changed by varying the thickness of object and temperature. The repulsive force would provide a method to deal with the stiction problems and bring much meaningful from practical views.

Repulsive and attractive Casimir interactions in liquids

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.
