Non-retarded room temperature Hamaker constants between elemental metals
摘要：
利用范德瓦尔斯力的Lifshitz理论，系统地计算了26种相同的各向同性金属元素在真空或纯水中的非延迟室温Hamaker常数。全谱方法，补充了德鲁德式低频外推，元素金属受益于扩展的频率可靠的介电数据的可用性。简单的光谱方法被用于纯水和三个介电表象进行了探索。数值截断和低频外推的影响是可以忽略不计的。常见的Lifshitz近似的准确性进行量化。Hamaker常数为100种金属组合的报告，几何混合规则被发现是高度准确的真空和水。
英文摘要：
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.
