CIPSI对苯的基态电子能的影响

The performance of CIPSI on the ground state electronic energy of benzene

Pierre-François Loos, Yann Damour, Anthony Scemama

摘要:

根据Eriksen等人[arXiv:2008.02678]的最新工作,我们报告了\textit{Configuration Interaction using a Perturbative Selection made Iteratively}(CIPSI)方法在cc-pVDZ基础上对苯分子的非相对论冻结核相关能的性能。按照我们通常的协议,我们得到的相关能$-863.4$ m $E_h$同意的理论估计$-863$ m $E_h$提出的Eriksen等人。使用广泛的阵列的高精度的新的电子结构方法。

英文摘要:

Following the recent work of Eriksen et al. [arXiv:2008.02678], we report the performance of the \textit{Configuration Interaction using a Perturbative Selection made Iteratively} (CIPSI) method on the non-relativistic frozen-core correlation energy of the benzene molecule in the cc-pVDZ basis. Following our usual protocol, we obtain a correlation energy of $-863.4$ m$E_h$ which agrees with the theoretical estimate of $-863$ m$E_h$ proposed by Eriksen et al. using an extensive array of highly-accurate new electronic structure methods.
