Abstract 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 & water.

元素金属之间的非延迟室温 Hamaker 常数

摘要 利用范德华力的 Lifshitz 理论，系统计算了嵌入真空或纯水中的 26 种相同的各向同性元素金属之间的非延迟室温 Hamaker 常数。全光谱方法，辅以类似德鲁德的低频外推法，用于元素金属，受益于扩展频率可靠介电数据的可用性。对纯水采用简单的光谱方法，并探索了三种介电表示。数值截断和低频外推效应显示可以忽略不计。常见 Lifshitz 近似的准确度被量化。报告了 100 种金属组合的 Hamaker 常数；显示几何混合规则在真空和水中高度准确。
