Repulsive Casimir force between silicon dioxide and superconductor

Authors


Abstract

We present a detailed investigation of the Casimir interaction between the superconductor Bi2Sr2CaCu2O8+δ (BSCCO) and silicon dioxide with bromobenzene present in between. We found that the dispersion force is repulsive and the magnitude of the force can be changed by varying the thickness of the object and the temperature. The repulsive force would provide a method to deal with stiction problems and provide much significant from the practical point of view. (© 2012 WILEY-VCH Verlag GmbH & Co. KGaA, Weinheim)
