摘要:

我们推导出了两个无限长的各向异性半导体/绝缘薄圆柱体之间的范德华色散相互作用的完整形式。推导是基于[J. N. Munday,D. Iannuzzi,Yu. S. Barash和F. Capasso,{ \sl Phys. Rev. A} { \bf 71},042102(2005)]。这个公式然后被用来计算一对单壁碳纳米管在所有的间距和所有的角度之间的色散相互作用。非延迟和延迟形式的相互作用分别开发。排斥色散相互作用和非单调色散相互作用的可能性进行了讨论的新配方的框架内。

英文摘要:

We derive the complete form of the van der Waals dispersion interaction between two infinitely long anisotropic semiconducting/insulating thin cylinders at all separations. The derivation is based on the general theory of dispersion interactions between anisotropic media as formulated in [J. N. Munday, D. Iannuzzi, Yu. S. Barash and F. Capasso, {\sl Phys. Rev. A} {\bf 71}, 042102 (2005)]. This formulation is then used to calculate the dispersion interactions between a pair of single walled carbon nanotubes at all separations and all angles. Non-retarded and retarded forms of the interactions are developed separately. The possibility of repulsive dispersion interactions and non-monotonic dispersion interactions is discussed within the framework of the new formulation.
