标题： Anisotropic contribution to the van der Waals and the Casimir-Polder energies for CO$_2$ and CH$_4$ molecules near surfaces and thin films

摘要： 为了理解二氧化碳（CO$_2$）和甲烷（CH$_4$）分子为何与表面相互作用不同，我们研究了线性极化的CO$_2$分子和各向同性极化的CH$_4$分子在原子薄金膜和非晶二氧化硅板前的卡西米尔-波尔德能量。 我们定量分析了分子极化率的各向异性如何影响分子结合能的范德华贡献。 显示英文摘要

摘要： In order to understand why carbon dioxide (CO$_2$) and methane (CH$_4$) molecules interact differently with surfaces, we investigate the Casimir-Polder energy of a linearly polarizable CO$_2$ molecule and an isotropically polarizable CH$_4$ molecule in front of an atomically thin gold film and an amorphous silica slab. We quantitatively analyze how the anisotropy in the polarizability of the molecule influences the van der Waals contribution to the binding energy of the molecule.
