基组的作用:评价密度泛函理论

The Role of the Basis Set: Assessing Density Functional Theory

A. Daniel Boese, Jan M. L. Martin, Nicholas C. Handy

摘要:

在发展和评价密度泛函理论方法时,通常采用有限基组。然而,在大多数情况下,基集依赖性的问题被忽视。在这里,我们评估几个基集和泛函。此外,依赖的半经验适合于一个给定的基组的广义梯度近似和混合功能的影响。然后对得到的泛函进行其他基组的测试,评估它们的误差和可转移性。

英文摘要:

When developing and assessing density functional theory methods, a finite basis set is usually employed. In most cases, however, the issue of basis set dependency is neglected. Here, we assess several basis sets and functionals. In addition, the dependency of the semiempirical fits to a given basis set for a generalised gradient approximation and a hybrid functional is investigated. The resulting functionals are then tested for other basis sets, evaluating their errors and transferability.
