圆柱间零点相互作用能的精确解

Exact zero-point interaction energy between cylinders

F. D. Mazzitelli, D. A. R. Dalvit, F. C. Lombardo

摘要:

我们计算精确的Casimir相互作用能量之间的两个完美的传导,很长,偏心圆柱壳使用模式求和技术。几个极限情况下的Casimir能量对应于这种配置的精确公式进行了研究分析和数值。这些包括同心圆柱体、圆柱平面和偏心圆柱体,用于表面之间的小间距和大间距。对于小的分离,我们恢复的邻近近似,而对于大的分离,我们发现一个弱的对数衰减的Casimir相互作用能,典型的圆柱形几何形状。

英文摘要:

We calculate the exact Casimir interaction energy between two perfectly conducting, very long, eccentric cylindrical shells using a mode summation technique. Several limiting cases of the exact formula for the Casimir energy corresponding to this configuration are studied both analytically and numerically. These include concentric cylinders, cylinder-plane, and eccentric cylinders, for small and large separations between the surfaces. For small separations we recover the proximity approximation, while for large separations we find a weak logarithmic decay of the Casimir interaction energy, typical of cylindrical geometries.
