论文摘要
范德华力的LIFSHITZ理论用于系统计算嵌入真空中或纯水中的26个相同的各向同性元素金属之间的非粘贴室温HAMAKER常数。完整的光谱方法与drude样低频外推的补充，用于从可获得扩展的频率可靠介电数据的可用性中受益的元素金属。简单的光谱方法用于纯水，并探索了三个介电表示。数值截断和低频外推效应被证明可以忽略不计。量化了公共Lifshitz近似值的准确性。报告了100个金属组合的Hamaker常数；几何混合规则显示在真空和水中非常准确。
The Lifshitz theory of van der Waals forces is utilized for the systematic calculation of the non-retarded room temperature Hamaker constants between 26 identical isotropic elemental metals that are embedded in vacuum or in pure water. The full spectral method, complemented with a Drude-like low frequency extrapolation, is employed for the elemental metals benefitting from the availability of extended-in-frequency reliable dielectric data. The simple spectral method is employed for pure water and three dielectric representations are explored. Numerical truncation and low frequency extrapolation effects are shown to be negligible. The accuracy of common Lifshitz approximations is quantified. The Hamaker constants for 100 metal combinations are reported; the geometric mixing rule is revealed to be highly accurate in vacuum and water.
