标题： Van der Waals interaction between microparticle and uniaxial crystal with application to hydrogen atoms and multiwall carbon nanotubes

摘要： 利夫希茨理论的范德华力被扩展到原子（分子）与单轴晶体平面表面或由各向同性材料或单轴晶体制成的长实心圆柱体或圆柱壳相互作用的情况。 对于靠近由单轴晶体制成的半空间或平板的微粒子，给出了范德华力和卡西米尔-波尔德相互作用自由能的精确表达式。 得到了微粒子-圆柱相互作用自由能的近似表达式，当微粒子-圆柱间距远小于圆柱半径时，该表达式变得精确。 所得到的表达式用于研究氢原子（分子）与石墨板或多壁碳纳米管之间的范德华相互作用。 为此，利用石墨寻常光和非常光的复折射率的光学数据，找到了石墨介电常数在虚频率轴上的行为。 结果表明，氢原子位于多壁碳纳米管内部比位于外部更具有能量优势。 显示英文摘要

摘要： The Lifshitz theory of the van der Waals force is extended for the case of an atom (molecule) interacting with a plane surface of an uniaxial crystal or with a long solid cylinder or cylindrical shell made of isotropic material or uniaxial crystal. For a microparticle near a semispace or flat plate made of an uniaxial crystal the exact expressions for the free energy of the van der Waals and Casimir-Polder interaction are presented. An approximate expression for the free energy of microparticle- cylinder interaction is obtained which becomes precise for microparticle-cylinder separations much smaller than cylinder radius. The obtained expressions are used to investigate the van der Waals interaction between hydrogen atoms (molecules) and graphite plates or multiwall carbon nanotubes. To accomplish this the behavior of graphite dielectric permittivities along the imaginary frequency axis is found using the optical data for the complex refractive index of graphite for the ordinary and extraordinary rays. It is shown that the position of hydrogen atoms inside multiwall carbon nanotubes is energetically preferable compared with outside.
